VARIATION, a deviation in the size, shape, or other feature of
a character or trait, from the mean or average of that character in the
species.
a character or trait, from the mean or average of that character in the
species.
Applied Eugenics by Roswell H. Johnson and Paul Popenoe
Many
others, such as baldness, are probably Mendelian but not yet
sufficiently supported by evidence.
None of these characters, it will be observed, is of much significance
eugenically. If the exact manner of inheritance of some of the more
important mental and physical traits were known, it would be of value.
But it is not a prerequisite for eugenic action. Enough is known for a
working program.
To sum up: the features in the modern view of heredity, which the reader
must keep in mind, are the following:
1. That the various characters which make up the physical constitution
of any individual plant or animal are due to the action (concurrently
with the environment, of course) of what are called, for convenience,
factors, separable hypothetical units in the germ-plasm, capable of
independent transmission.
2. That each visible character is due to the cooperative action of an
indefinitely large number of factors; conversely, that each of these
factors affects an indefinitely large number of characters.

APPENDIX F
GLOSSARY
ACQUIRED CHARACTER, a modification of a germinal trait after
cell fusion. It is difficult to draw a line between characters that are
acquired and those that are inborn. The idea involved is as follows: in
a standard environment, a given factor in the germ-plasm will develop
into a trait which varies not very widely about a certain mean. The mean
of this trait is taken as representing the germinal trait in its typical
condition. But if the environment be not standard, if it be considerably
changed, the trait will develop a variation far from the mean of that
trait in the species. Thus an American, whose skin in the standard
environment of the United States would be blonde, may under the
environment of Cuba develop into a brunette. Such a wide variation from
the mean thus caused is called an acquired character; it is usually
impressed on the organism after the germinal trait has reached a full,
typical development.
ALLELOMORPH (one another form), one of a pair of factors which
are alternative to each other in Mendelian inheritance. Instead of a
single pair, there may be a group of "multiple allelomorphs," each
member being alternative to every other member of the group.
ALLELOMORPHISM, a relation between two or more factors, such
that two which are present in one zygote do not both enter into the same
gamete, but are separated into sister gametes.
BIOMETRY (life measure), the study of biology by statistical
methods.
BRACHYDACTYLY (short-finger), a condition in which the bones,
particularly of the fingers and toes, fail to grow to their normal
length. In well-marked cases one of these is a reduction from three
phalanges or joints to two.
CHARACTER (a contraction of "characteristic"), a term which is
used, often rather vaguely, to designate any function, feature, or organ
of the body or mind.
CHROMOSOME (color body, so called from its affinity for certain
stains), a body of peculiar protoplasm, in the nucleus of the cell. Each
species has its own characteristic number; the cells of the human body
contain 24 chromosomes each.
CONGENITAL (with birth), present at birth. The term fails to
distinguish between traits which are actually inherited, and
modifications acquired during prenatal life. In the interest of clear
thinking its use should be avoided so far as possible.
CORRELATION (together relation), a relation between two
variables in a certain population, such that for every variation of one,
there is a corresponding variation of the other. Mathematically, two
correlated variables are thus mutually dependent. But a correlation is
merely a statistical description of a particular case, and in some other
population the same two variables might be correlated in a different
way, other influences being at work on them.
CYTOLOGY (cell word), the study of the cell, the constituent
unit of organisms.
DETERMINER (completely end), an element or condition in a
germ-cell, supposed to be essential to the development of a particular
quality, feature, or manner of reaction of the organism which arises
from that germ-cell. The word is gradually falling into disuse, and
"factor" taking its place.
DOMINANCE (mastery), in Mendelian hybrids the capacity of a
character which is derived from only one of two generating gametes to
develop to an extent nearly or quite equal to that exhibited by an
individual which has derived the same character from both of the
generating gametes. In the absence of dominance the given character of
the hybrid usually presents a "blend" or intermediate condition between
the two parents.
DYSGENIC (bad origin), tending to impair the racial qualities
of future generations; the opposite of eugenic.
ENDOGAMY (within mating), a custom of some primitive peoples,
in compliance with which a man must choose his wife from his own group
(clan, gens, tribe, etc. ).
EUGENIC (good origin), tending to improve the racial qualities
of future generations, either physical or mental.
EUTHENIC (good thriving), tending to produce beneficial
acquired characters or better conditions for people to live in, but not
tending (except incidentally and indirectly) to produce people who can
hand on the improvement by heredity.
EVOLUTION (unroll), ORGANIC, the progressive change of
living forms, usually associated with the development of complex from
simple forms.
EXOGAMY (out mating), a custom of primitive peoples which
requires a man to choose a wife from some other group (clan, gens,
tribe, etc. ) than his own.
FACTOR (maker), a name given to the hypothetical _something_,
the independently inheritable element in the germ-cell, whose presence
is necessary to the development of a certain inherited character or
characters or contributes with other factors to the development of a
character. "Gene" and "determiner" are sometimes used as synonyms of
factor.
FEEBLE-MINDEDNESS, a condition in which mental development is
retarded or incomplete. It is a relative term, since an individual who
would be feeble-minded in one society might be normal or even bright in
another. The customary criterion is the inability of the individual,
because of mental defect existing from an early age, to compete on equal
terms with his normal fellows, or to manage himself or his affairs with
ordinary prudence. American students usually distinguish three grades of
mental defect: Idiots are those who are unable to take care of
themselves, even to the extent of guarding against common physical
dangers or satisfying physical needs. Their mentality does not progress
beyond that of a normal two-year-old child. Imbeciles can care for
themselves after a fashion, but are unable to earn their living. Their
mental ages range from three to seven years, inclusive. Morons, who
correspond to the common acceptation of the term feeble-minded, "can
under proper direction become more or less self-supporting but they are
as a rule incapable of undertaking affairs which demand judgment or
involve unrestricted competition with normal individuals. Their
intelligence ranges with that of normal children from seven to twelve
years of age. " There is necessarily a considerable borderline, but any
adult whose intelligence is beyond that of the normal twelve-year-old
child is usually considered to be not feeble-minded.
GAMETE (mate), a mature germ-cell; in animals an ovum or
spermatozoon.
GENETICS (origins), for a long time meant the study of
evolution by experimental breeding and was often synonomous with
Mendelism. It is gradually returning to its broader, original meaning of
the study of variation and heredity, that is, the origin of the
individual's traits. This broader meaning is preferable.
GERMINAL (sprig), due to something present in the germ-cell. A
trait is germinal when its basis is inherited,--as eye color,--and when
it develops with nothing more than the standard environment; remaining
relatively constant from one generation to another, except as influenced
by reproduction.
GERM-PLASM (sprig form), mature germ-cells and the living
material from which they are produced.
HAEMOPHILIA (blood love), an inability of the blood to clot. It
thus becomes impossible to stop the flow of blood from a cut, and one
who has inherited haemophilia usually dies sooner or later from
haemorrhage.
HEREDITY (heirship), is usually considered from the outside,
when it may properly be defined as organic resemblance based on descent,
or the correlation between relatives. But a better definition, based on
the results of genetics, looks at it as a mechanism, not as an external
appearance. From this point of view, heredity may be said to be "the
persistence of certain cell-constituents (in the germ-cells) through an
unending number of cell-divisions. "
HETEROZYGOTE (different yolk), a zygotic individual which
contains both members of an allelomorphic pair.
HOMOZYGOTE (same yolk), an individual which contains only one
member of an allelomorphic pair, but contains that in duplicate, having
received it from both parents. A homozygous individual, having been
formed by the union of like gametes, in turn regularly produces gametes
of only one kind with respect to any given factor, thus giving rise to
offspring which are, in this regard, like the parents; in other words,
homozygotes regularly "breed true. " An individual may be a homozygote
with respect to one factor and a heterozygote with respect to another.
HORMONES (chain), the secretions of various internal glands,
which are carried in the blood and have an important specific influence
on the growth and functioning of various parts of the body. Their exact
nature is not yet understood.
INBORN usually means germinal, as applied to a trait, and it is
so used in this book. Strictly speaking, however, any trait which
appears in a child at birth might be called inborn, and some writers,
particularly medical men, thus refer to traits acquired in prenatal
life. Because of this ambiguity the word should be carefully defined
when used, or avoided.
INHERENT (in stick), as used in this book, is synonymous with
germinal.
INDUCTION (in lead), a change brought about in the germ-plasm
with the effect of temporarily modifying the characters of an
individual produced from that germ-plasm; but not of changing in a
definite and permanent way any such germ-plasm and therefore any
individual inherited traits.
INNATE (inborn), synonymous with inborn.
LATENT (lie hidden), a term applied to traits or characters
whose factors exist in the germ-plasm of an individual, but which are
not visible in his body.
LAW, in natural science means a concise and comprehensive
description of an observed uniform sequence of events. It is thus quite
different from the law of jurists, who mean a rule laid down for the
guidance of an intelligent being, by an intelligent being having power
over him.
MENDELISM, a collection of laws of heredity (see Appendix D)
so-called after the discoverer of the first of them to become known;
also the analytical study of heredity with a view to learning the
constitution of the germ-cells of animals and plants.
MENDELIZE, to follow Mendel's laws of inheritance.
MORES (customs), the approved customs or unwritten laws of a
people; the conventions of society; popular usage or folk-ways which are
reputable.
MUTATION (change), has now two accepted meanings: (1) a
profound change in the germ-plasm of an organism such as will produce
numerous changes in its progeny; and (2) a discontinuous heritable
change in a Mendelian factor. It is used in the first sense by De Vries
and other "mutationists" and in the second sense by Morgan and other
Mendelists; confusion has arisen from failure to note the difference in
usage.
NORMAL CURVE, the curve of distribution of variations of
something whose variations are due to a multiplicity of causes acting
nearly equally in both directions. It is characterized by having more
individuals of a mediocre degree and progressively fewer above and below
this mode.
NUCLEUS (little nut), a central, highly-organized part of every
living cell, which seems to play a directive role in cell-development
and contains, among other things, the chromosomes.
PATENT (lie open), a term applied to traits which are
manifestly represented in the body as well as the germ-plasm of an
individual. The converse of "latent. "
PROBABILITY CURVE, the same as normal curve. Also called a
Gaussian curve.
PROTOPLASM (first form), "the physical basis of life"; a
chemical compound or probably an emulsion of numerous compounds. It
contains proteins which differ slightly in many species of organism. It
contains carbon, hydrogen, oxygen, nitrogen, sulphur, and various salts,
but is so complex as to defy exhaustive analysis.
PSYCHIATRY (soul healing), the study of diseases of the mind.
RECESSIVE (draw back), the converse of dominant; applied to one
of a pair of contrasted Mendelian characters which can not appear in the
presence of the other.
REGRESSION (back go), the average variation of one variable for
a unit variation of a correlated variable.
SEGREGATION (aside flock), (1) as used in eugenics means the
policy of isolating feeble-minded and other anti-social individuals from
the normal population into institutions, colonies, etc. , where the two
sexes are kept apart. (2) The term is also used technically in genetics,
to refer to the discontinuity of the variation of characteristics
resulting from the independent distribution of factors before or at the
time of formation of the gametes.
SELECTION (apart pick), the choice (for perpetuation by
reproduction) from a mixed population, of the individuals possessing in
common a certain character or a certain degree of some character. Two
kinds of selection may be distinguished: (1) natural selection, in which
choice is made automatically by the failure to reproduce (through death
or some other cause) of the individuals who are not "fit" to pass the
tests of the environment (vitality, disease resistance, speed, success
in mating, or what not); and (2) artificial selection, in which the
choice is made consciously by man, as a livestock breeder.
SEX-LIMITED, a term applied to traits which differ in the two
sexes, because influenced by the hormones of the reproductive glands.
Example, the beard.
SEX-LINKED, a term applied to traits which are connected with
sex _accidentally_ and not physiologically in development. The current
explanation is that such traits happen to be in the same chromosome as
the determiner of maleness or femaleness, as the case may be.
Color-blindness is the classical example in man.
SEXUAL SELECTION, the conscious or unconscious preference by
individuals of one sex, or by that sex as a whole, for individuals of
the other sex who possess some particular attribute or attributes in a
degree above or below the average of their sex. If the deviation of the
chosen character is in the same direction (plus or minus) as in the
chooser, the mating is called assortative; if in one direction
independent of the characteristic of the chooser, it is called
preferential.
SOMA (body), the body as distinguished from the germ-plasm.
From this point of view every individual consists of only two
parts,--germ-plasm and soma or somatoplasm.
TRAIT, a term used by geneticists as a synonym of "character. "
UNIT-CHARACTER, in Mendelian heredity a character or
alternative difference of any kind, which is apparently not capable of
subdivision in heredity, but is inherited as a whole, and which is
capable of becoming associated in new combinations with other
characters. The term is now going out of use, as it makes for clearer
thinking about heredity to fix the attention on the factors of the
germ-cells instead of on the characters of the adult.
VARIATION, a deviation in the size, shape, or other feature of
a character or trait, from the mean or average of that character in the
species.
VESTIGIAL (footstep), a term applied to a character which at
some time in the evolutionary history of the species possessed
importance, or functioned fully, but which has now lost its importance
or its original use, so that it remains a mere souvenir of the past, in
a degenerated condition. Example, the muscles which move a man's ears.
ZYGOTE (yolk), the fertilized egg-cell; the united cell formed
by the union of the ovum and spermatozoon after fertilization.
ZYMOTIC, caused by a microorganism,--a term applied to
diseases. Example, tuberculosis.

others, such as baldness, are probably Mendelian but not yet
sufficiently supported by evidence.
None of these characters, it will be observed, is of much significance
eugenically. If the exact manner of inheritance of some of the more
important mental and physical traits were known, it would be of value.
But it is not a prerequisite for eugenic action. Enough is known for a
working program.
To sum up: the features in the modern view of heredity, which the reader
must keep in mind, are the following:
1. That the various characters which make up the physical constitution
of any individual plant or animal are due to the action (concurrently
with the environment, of course) of what are called, for convenience,
factors, separable hypothetical units in the germ-plasm, capable of
independent transmission.
2. That each visible character is due to the cooperative action of an
indefinitely large number of factors; conversely, that each of these
factors affects an indefinitely large number of characters.

APPENDIX F
GLOSSARY
ACQUIRED CHARACTER, a modification of a germinal trait after
cell fusion. It is difficult to draw a line between characters that are
acquired and those that are inborn. The idea involved is as follows: in
a standard environment, a given factor in the germ-plasm will develop
into a trait which varies not very widely about a certain mean. The mean
of this trait is taken as representing the germinal trait in its typical
condition. But if the environment be not standard, if it be considerably
changed, the trait will develop a variation far from the mean of that
trait in the species. Thus an American, whose skin in the standard
environment of the United States would be blonde, may under the
environment of Cuba develop into a brunette. Such a wide variation from
the mean thus caused is called an acquired character; it is usually
impressed on the organism after the germinal trait has reached a full,
typical development.
ALLELOMORPH (one another form), one of a pair of factors which
are alternative to each other in Mendelian inheritance. Instead of a
single pair, there may be a group of "multiple allelomorphs," each
member being alternative to every other member of the group.
ALLELOMORPHISM, a relation between two or more factors, such
that two which are present in one zygote do not both enter into the same
gamete, but are separated into sister gametes.
BIOMETRY (life measure), the study of biology by statistical
methods.
BRACHYDACTYLY (short-finger), a condition in which the bones,
particularly of the fingers and toes, fail to grow to their normal
length. In well-marked cases one of these is a reduction from three
phalanges or joints to two.
CHARACTER (a contraction of "characteristic"), a term which is
used, often rather vaguely, to designate any function, feature, or organ
of the body or mind.
CHROMOSOME (color body, so called from its affinity for certain
stains), a body of peculiar protoplasm, in the nucleus of the cell. Each
species has its own characteristic number; the cells of the human body
contain 24 chromosomes each.
CONGENITAL (with birth), present at birth. The term fails to
distinguish between traits which are actually inherited, and
modifications acquired during prenatal life. In the interest of clear
thinking its use should be avoided so far as possible.
CORRELATION (together relation), a relation between two
variables in a certain population, such that for every variation of one,
there is a corresponding variation of the other. Mathematically, two
correlated variables are thus mutually dependent. But a correlation is
merely a statistical description of a particular case, and in some other
population the same two variables might be correlated in a different
way, other influences being at work on them.
CYTOLOGY (cell word), the study of the cell, the constituent
unit of organisms.
DETERMINER (completely end), an element or condition in a
germ-cell, supposed to be essential to the development of a particular
quality, feature, or manner of reaction of the organism which arises
from that germ-cell. The word is gradually falling into disuse, and
"factor" taking its place.
DOMINANCE (mastery), in Mendelian hybrids the capacity of a
character which is derived from only one of two generating gametes to
develop to an extent nearly or quite equal to that exhibited by an
individual which has derived the same character from both of the
generating gametes. In the absence of dominance the given character of
the hybrid usually presents a "blend" or intermediate condition between
the two parents.
DYSGENIC (bad origin), tending to impair the racial qualities
of future generations; the opposite of eugenic.
ENDOGAMY (within mating), a custom of some primitive peoples,
in compliance with which a man must choose his wife from his own group
(clan, gens, tribe, etc. ).
EUGENIC (good origin), tending to improve the racial qualities
of future generations, either physical or mental.
EUTHENIC (good thriving), tending to produce beneficial
acquired characters or better conditions for people to live in, but not
tending (except incidentally and indirectly) to produce people who can
hand on the improvement by heredity.
EVOLUTION (unroll), ORGANIC, the progressive change of
living forms, usually associated with the development of complex from
simple forms.
EXOGAMY (out mating), a custom of primitive peoples which
requires a man to choose a wife from some other group (clan, gens,
tribe, etc. ) than his own.
FACTOR (maker), a name given to the hypothetical _something_,
the independently inheritable element in the germ-cell, whose presence
is necessary to the development of a certain inherited character or
characters or contributes with other factors to the development of a
character. "Gene" and "determiner" are sometimes used as synonyms of
factor.
FEEBLE-MINDEDNESS, a condition in which mental development is
retarded or incomplete. It is a relative term, since an individual who
would be feeble-minded in one society might be normal or even bright in
another. The customary criterion is the inability of the individual,
because of mental defect existing from an early age, to compete on equal
terms with his normal fellows, or to manage himself or his affairs with
ordinary prudence. American students usually distinguish three grades of
mental defect: Idiots are those who are unable to take care of
themselves, even to the extent of guarding against common physical
dangers or satisfying physical needs. Their mentality does not progress
beyond that of a normal two-year-old child. Imbeciles can care for
themselves after a fashion, but are unable to earn their living. Their
mental ages range from three to seven years, inclusive. Morons, who
correspond to the common acceptation of the term feeble-minded, "can
under proper direction become more or less self-supporting but they are
as a rule incapable of undertaking affairs which demand judgment or
involve unrestricted competition with normal individuals. Their
intelligence ranges with that of normal children from seven to twelve
years of age. " There is necessarily a considerable borderline, but any
adult whose intelligence is beyond that of the normal twelve-year-old
child is usually considered to be not feeble-minded.
GAMETE (mate), a mature germ-cell; in animals an ovum or
spermatozoon.
GENETICS (origins), for a long time meant the study of
evolution by experimental breeding and was often synonomous with
Mendelism. It is gradually returning to its broader, original meaning of
the study of variation and heredity, that is, the origin of the
individual's traits. This broader meaning is preferable.
GERMINAL (sprig), due to something present in the germ-cell. A
trait is germinal when its basis is inherited,--as eye color,--and when
it develops with nothing more than the standard environment; remaining
relatively constant from one generation to another, except as influenced
by reproduction.
GERM-PLASM (sprig form), mature germ-cells and the living
material from which they are produced.
HAEMOPHILIA (blood love), an inability of the blood to clot. It
thus becomes impossible to stop the flow of blood from a cut, and one
who has inherited haemophilia usually dies sooner or later from
haemorrhage.
HEREDITY (heirship), is usually considered from the outside,
when it may properly be defined as organic resemblance based on descent,
or the correlation between relatives. But a better definition, based on
the results of genetics, looks at it as a mechanism, not as an external
appearance. From this point of view, heredity may be said to be "the
persistence of certain cell-constituents (in the germ-cells) through an
unending number of cell-divisions. "
HETEROZYGOTE (different yolk), a zygotic individual which
contains both members of an allelomorphic pair.
HOMOZYGOTE (same yolk), an individual which contains only one
member of an allelomorphic pair, but contains that in duplicate, having
received it from both parents. A homozygous individual, having been
formed by the union of like gametes, in turn regularly produces gametes
of only one kind with respect to any given factor, thus giving rise to
offspring which are, in this regard, like the parents; in other words,
homozygotes regularly "breed true. " An individual may be a homozygote
with respect to one factor and a heterozygote with respect to another.
HORMONES (chain), the secretions of various internal glands,
which are carried in the blood and have an important specific influence
on the growth and functioning of various parts of the body. Their exact
nature is not yet understood.
INBORN usually means germinal, as applied to a trait, and it is
so used in this book. Strictly speaking, however, any trait which
appears in a child at birth might be called inborn, and some writers,
particularly medical men, thus refer to traits acquired in prenatal
life. Because of this ambiguity the word should be carefully defined
when used, or avoided.
INHERENT (in stick), as used in this book, is synonymous with
germinal.
INDUCTION (in lead), a change brought about in the germ-plasm
with the effect of temporarily modifying the characters of an
individual produced from that germ-plasm; but not of changing in a
definite and permanent way any such germ-plasm and therefore any
individual inherited traits.
INNATE (inborn), synonymous with inborn.
LATENT (lie hidden), a term applied to traits or characters
whose factors exist in the germ-plasm of an individual, but which are
not visible in his body.
LAW, in natural science means a concise and comprehensive
description of an observed uniform sequence of events. It is thus quite
different from the law of jurists, who mean a rule laid down for the
guidance of an intelligent being, by an intelligent being having power
over him.
MENDELISM, a collection of laws of heredity (see Appendix D)
so-called after the discoverer of the first of them to become known;
also the analytical study of heredity with a view to learning the
constitution of the germ-cells of animals and plants.
MENDELIZE, to follow Mendel's laws of inheritance.
MORES (customs), the approved customs or unwritten laws of a
people; the conventions of society; popular usage or folk-ways which are
reputable.
MUTATION (change), has now two accepted meanings: (1) a
profound change in the germ-plasm of an organism such as will produce
numerous changes in its progeny; and (2) a discontinuous heritable
change in a Mendelian factor. It is used in the first sense by De Vries
and other "mutationists" and in the second sense by Morgan and other
Mendelists; confusion has arisen from failure to note the difference in
usage.
NORMAL CURVE, the curve of distribution of variations of
something whose variations are due to a multiplicity of causes acting
nearly equally in both directions. It is characterized by having more
individuals of a mediocre degree and progressively fewer above and below
this mode.
NUCLEUS (little nut), a central, highly-organized part of every
living cell, which seems to play a directive role in cell-development
and contains, among other things, the chromosomes.
PATENT (lie open), a term applied to traits which are
manifestly represented in the body as well as the germ-plasm of an
individual. The converse of "latent. "
PROBABILITY CURVE, the same as normal curve. Also called a
Gaussian curve.
PROTOPLASM (first form), "the physical basis of life"; a
chemical compound or probably an emulsion of numerous compounds. It
contains proteins which differ slightly in many species of organism. It
contains carbon, hydrogen, oxygen, nitrogen, sulphur, and various salts,
but is so complex as to defy exhaustive analysis.
PSYCHIATRY (soul healing), the study of diseases of the mind.
RECESSIVE (draw back), the converse of dominant; applied to one
of a pair of contrasted Mendelian characters which can not appear in the
presence of the other.
REGRESSION (back go), the average variation of one variable for
a unit variation of a correlated variable.
SEGREGATION (aside flock), (1) as used in eugenics means the
policy of isolating feeble-minded and other anti-social individuals from
the normal population into institutions, colonies, etc. , where the two
sexes are kept apart. (2) The term is also used technically in genetics,
to refer to the discontinuity of the variation of characteristics
resulting from the independent distribution of factors before or at the
time of formation of the gametes.
SELECTION (apart pick), the choice (for perpetuation by
reproduction) from a mixed population, of the individuals possessing in
common a certain character or a certain degree of some character. Two
kinds of selection may be distinguished: (1) natural selection, in which
choice is made automatically by the failure to reproduce (through death
or some other cause) of the individuals who are not "fit" to pass the
tests of the environment (vitality, disease resistance, speed, success
in mating, or what not); and (2) artificial selection, in which the
choice is made consciously by man, as a livestock breeder.
SEX-LIMITED, a term applied to traits which differ in the two
sexes, because influenced by the hormones of the reproductive glands.
Example, the beard.
SEX-LINKED, a term applied to traits which are connected with
sex _accidentally_ and not physiologically in development. The current
explanation is that such traits happen to be in the same chromosome as
the determiner of maleness or femaleness, as the case may be.
Color-blindness is the classical example in man.
SEXUAL SELECTION, the conscious or unconscious preference by
individuals of one sex, or by that sex as a whole, for individuals of
the other sex who possess some particular attribute or attributes in a
degree above or below the average of their sex. If the deviation of the
chosen character is in the same direction (plus or minus) as in the
chooser, the mating is called assortative; if in one direction
independent of the characteristic of the chooser, it is called
preferential.
SOMA (body), the body as distinguished from the germ-plasm.
From this point of view every individual consists of only two
parts,--germ-plasm and soma or somatoplasm.
TRAIT, a term used by geneticists as a synonym of "character. "
UNIT-CHARACTER, in Mendelian heredity a character or
alternative difference of any kind, which is apparently not capable of
subdivision in heredity, but is inherited as a whole, and which is
capable of becoming associated in new combinations with other
characters. The term is now going out of use, as it makes for clearer
thinking about heredity to fix the attention on the factors of the
germ-cells instead of on the characters of the adult.
VARIATION, a deviation in the size, shape, or other feature of
a character or trait, from the mean or average of that character in the
species.
VESTIGIAL (footstep), a term applied to a character which at
some time in the evolutionary history of the species possessed
importance, or functioned fully, but which has now lost its importance
or its original use, so that it remains a mere souvenir of the past, in
a degenerated condition. Example, the muscles which move a man's ears.
ZYGOTE (yolk), the fertilized egg-cell; the united cell formed
by the union of the ovum and spermatozoon after fertilization.
ZYMOTIC, caused by a microorganism,--a term applied to
diseases. Example, tuberculosis.
