Oogenesis starts in the foetus at around 7 weeks' gestation, when primordial germ cells colonize the newly formed ovary. They are now referred to as oogonia.16. Oogonia undergo mitosis or rapid proliferation (multiplication). WebOogenesis—the differentiation of the ovum—differs from spermatogenesis in several ways. Whereas the gamete formed by spermatogenesis is essentially a motile nucleus, the gamete formed by oogenesis contains all the materials needed to initiate and maintain metabolism and development. Therefore, in addition to forming a haploid nucleus, oogenesis also … cristina suriani
