Definition: Of or pertaining to sex, or the sexes; distinguishing sex;
peculiar to the distinction and office of male or female; relating to
the distinctive genital organs of the sexes; proceeding from, or
based upon, sex; as, sexual characteristics; sexual intercourse,
connection, or commerce; sexual desire; sexual diseases; sexual
generation. Sexual dimorphism (Biol.), the condition of having one of
the sexes existing in two forms, or varieties, differing in color,
size, etc., as in many species of butterflies which have two kinds of
females.
– Sexual method (Bot.), a method of classification proposed by
Linnæus, founded mainly on difference in number and position of the
stamens and pistils of plants.
– Sexual selection (Biol.), the selective preference of one sex for
certain characteristics in the other, such as bright colors, musical
notes, etc.; also, the selection which results from certain
individuals of one sex having more opportunities of pairing with the
other sex, on account of greater activity, strength, courage, etc.;
applied likewise to that kind of evolution which results from such
sexual preferences. Darwin.
In these cases, therefore, natural selection seems to have acted
independently of sexual selection. A. R. Wallace.
