WebGametogenesis. Gametogenesis is the process in which the formation of gametes takes place. Gametogenesis in males is known as spermatogenesis, and in females, it is termed oogenesis. Gametogenesis involves the formation of gametes from germ cells by both mitotic cell divisions and meiosis. First, spermatogenesis gets completed in the testes. WebGametogenesis (Spermatogenesis and Oogenesis) Gametogenesis, the production of sperm and eggs, takes place through the process of meiosis. During meiosis, two cell divisions separate the paired chromosomes in the nucleus and then separate the chromatids that were made during an earlier stage of the cell’s life cycle.

Some algae and the oomycetes produce eggs in oogonia. In the brown alga Fucus, all four egg cells survive oogenesis, which is an exception to the rule that generally only one product of female meiosis survives to maturity. In plants, oogenesis occurs inside the female gametophyte via mitosis. In many plants such as bryophytes, ferns, and gymnosperms, egg cells are formed in ar…
