reproduction

[rē′prəduk′shən]

Etymology: L, re + producere, to produce

1 the sum of the cellular and genetic phenomena by which organisms produce offspring similar to themselves so that the species is perpetuated. In humans the germ cells, spermatozoa in the male and ova in the female, unite during fertilization to form the new individual. Kinds of reproduction include asexual reproduction, cytogenic reproduction, and sexual reproduction.

2 the creation of a similar structure, situation, or phenomenon; duplication; replication.

3 the recalling of a former idea or impression or of something previously learned. reproductive, adj.

reproduction

1. the process by which a living entity or organism produces a new individual of the same kind. It may be asexual or sexual.

2. the creation of a similar object or situation; duplication; replication.

In sexual reproduction the gonads, or sex glands—the ovaries in the female and the testes in the male—produce the germ cells that unite and grow into a new individual. Reproduction begins when the germ cells unite, the process called fertilization.
