What are types of germ cells? Germ cells can either be male or female. Male germ...
WebSexual reproduction requires that diploid (2 n) organisms produce haploid (1 n) cells through meiosis and that these haploid cells fuse to form new, diploid offspring. The union of these two haploid cells, one from each parent, is fertilization. Although the processes of meiosis and mitosis share similarities, their end products are different. WebApr 4, 2024 · Sperm cells are continually being produced by the testes, but not all areas of the seminiferous tubules produce sperm cells at the same time. One immature germ cell takes as long as 74 days to reach final …
WebThe production of sperm and eggs/ova (gametes) is a procedure called gametogenesis (spermatogenesis and oogenesis). Gametogenesis involves two rounds of meiotic cell … WebAug 8, 2024 · This process is called “mitosis.” In gamete production, a different form of cell division occurs called “meiosis.” The outcome of meiosis is the creation of four daughter cells, either sperm or egg cells, through reduction division which results in a haploid complement of chromosomes in each gamete.
