Gametogenesis [Gr. gamos - a marriage; Gr. genesis - origin, descent]. The formation of male and female sex cells or gametes (spermatozoa and ova, respectively) from germ cells.

Gametogenesis Gametogenesis is the formation of gametes. The formation of eggs is oogenesis and the formation of sperm is spermatogenesis. In animals, gametes are formed by meiosis.
gametogenesis The formation of gametes by way of meiosis. gametogony Multiple fission that forms gametes that fuse to form a zygote. Also called gamogony. Occurs in the class Sporozoea.
Gametogenesis is the process of forming gametes (by definition haploid, n) from diploid cells of the germ line.
In females gametogenesis is known as oogenesis and unlike males, all of the primary oocytes ever found in a female will be created in the ovarian follicles of the ovaries prior to birth.
(2) A mature haploid reproductive cell as produced by gametogenesis, a process involving meiosis (3) A cell that fuses with another reproductive cell of the opposite sex during fertilization forming a zygote that develops into a new individual.
Animal life cycles have meiosis followed immediately by gametogenesis. Gametes are produced directly by meiosis. Male gametes are sperm. Female gametes are eggs or ova.
