WebThe parthenogenesis may be of two types: ADVERTISEMENTS: 1. Natural parthenogenesis. 2. Artificial parthenogenesis. 1. Natural Parthenogenesis: In certain … Parthenogenesis can occur without meiosis through mitotic oogenesis. This is called apomictic parthenogenesis. Mature egg cells are produced by mitotic divisions, and these cells directly develop into embryos. In flowering plants, cells of the gametophyte can undergo this process. The offspring produced … See more Parthenogenesis is a natural form of asexual reproduction in which growth and development of embryos occur in a gamete (egg or sperm) without combining with another gamete (e.g., egg and sperm fusing). In See more Gynogenesis A form of asexual reproduction related to parthenogenesis is gynogenesis. Here, offspring are produced by the same mechanism as in parthenogenesis, but with the requirement that the egg merely be stimulated by … See more • Dawley, Robert M. & Bogart, James P. (1989).
