Gametes produced from one meiotic event
WebPart 3: Mammalian Gametogenesis. The formation of gametes, or gametogenesis, is the first stage in sexual reproduction. In single-celled organisms, e.g., many Protista, the vegetative cell can simply act as a gamete. In more complex organisms specialized regions within the organism take on the role of gametogenesis.
