WebMultiplication phase In the multiplication phase, the spermatogonia or the male germ cells, which are diploid cells, undergo mitotic divisions and form a large number of spermatogonia. Growth phase During the growth phase, the spermatogonia accumulate nutrition in the cytoplasm and become large in size. Web24 de jan. de 2024 · Gametogenesis refers to spermatogenesis and oogenesis. Former is the process of formation of sperms while later is the process of formation of egg cells. These are reproductive cells without which continuation of a species is impossible. So, it can be said that gametogenesis is the preparatory phase for the process of reproduction.
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.

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.
