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.
