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.
