Meiosis leads to the formation of gametes
Web24 mrt. 2011 · Both males and females use meiosis to produce their gametes, although there are some key differences between the sexes at certain stages. In females, the process of meiosis is called oogenesis, since it produces oocytes and ultimately yields mature ova (eggs). The male counterpart is spermatogenesis, the production of sperm. WebSecond, the gametes are formed by meiosis followed by mitotic divisions and differentiation. In plants, the female gametes (the egg cell and the central ... dominant …
