Gametogenesis is a biological process by which diploid or haploid precursor cells undergo cell division and differentiation to form mature haploid gametes. Depending on the biological life cycle of the organism, gametogenesis occurs by meiotic division of diploid gametocytes into various gametes, or by mitosis. For example, plants produce gametes through mitosis in gametophytes. The gamet… Web• Gametogenesis is the production of gametes. ... – Meiosis results in haploid cells; mitosis results in diploid cells. ... • The genes for this fruit fly’s reddish-orange eyes and miniature wings are almost always inherited together.
