Oogenesis function and process
Web4 de set. de 2024 · A gamete produced by a female is called an egg, and the process that produces a mature egg is called oogenesis. Just one egg is produced from the four haploid cells that result from meiosis. The single egg is a very large cell, as you can see from the human egg also shown in Figure 7.5. 5. WebOogenesis in mammals: In mammals the process of oogenesis shows the following three phases: 1. Phase of multiplication: The primordial germ cells become the oogonia—the egg mother cell. The oogonial cells eventually undergo proliferation by repeated mitotic divisions, giving rise to the eggs and become primary oocytes when cell division ceases.

The body axes of Drosophila are established during oogenesis through reciprocal interactions between the germ line cells and the somatic follicle cells that surround them.
