Weboogenesis: [noun] the process of female gamete formation including formation of an oocyte from an oogonium (see oogonium 2) followed by meiotic division. 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 …
