Re`pro*duc"tion (-d?k"sh?n), n. [Cf. F.
reproduction.] 1. The act or process of
reproducing; the state of being reproduced; specifically
(Biol.), the process by which plants and animals give rise
to offspring.
&fist; There are two distinct methods of reproduction; viz.:
asexual reproduction (agamogenesis) and sexual
reproduction (gamogenesis). In both cases the new individual is
developed from detached portions of the parent organism. In asexual
reproduction (gemmation, fission, etc.), the detached portions of the
organism develop into new individuals without the intervention of
other living matter. In sexual reproduction, the detached portion,
which is always a single cell, called the female germ cell, is
acted upon by another portion of living matter, the male germ
cell, usually from another organism, and in the fusion of the two
(impregnation) a new cell is formed, from the development of which
arises a new individual.
2. That which is reproduced.
