WebThe molecular mechanisms underlying and determining egg developmental competence remain poorly understood in vertebrates. Nucleoplasmin (Npm2) is one of the few known maternal effect genes in mammals, but this maternal effect has never been demonstrated in nonmammalian species. A link between developmental competence and the abundance … WebOogenesis is the type of gametogenesis through which ova, also called the female gametes are formed and the produced female gamete is known as an ovum. In general terms, the female gametes are referred to as eggs, but the word egg can involve various stages of development, therefore, the significance of an egg varies based on the type of organisms.
Weboogenesis, in the human female reproductive system, growth process in which the primary egg cell (or ovum) becomes a mature ovum. In any one human generation, the egg’s development starts before the female that carries it is even born; 8 to 20 weeks after the fetus has started to grow, cells that are to become mature ova have been multiplying, …

Gametogenesis occurs when a haploid cell (n) is formed from a diploid cell (2n) through meiosis. We call gametogenesis in the male spermatogenesis and it produces spermatozoa. In the female, we call it oogenesis. It results in the formation of ova.
