Oogenesis formation
WebOogenesis—the differentiation of the ovum—differs from spermatogenesis in several ways. Whereas the gamete formed by spermatogenesis is essentially a motile nucleus, the … Webspermatogenesis oogenesis gamete. gametogenesis, in embryology, the process by which gametes, or germ cells, are produced in an organism. The formation of egg cells, or ova, is technically called oogenesis, and the formation of sperm cells, or spermatozoa, is called spermatogenesis. This article was most recently revised and updated by Michael Ray.
