WebMeiosis is the process of cell division which gives rise to gametes. For the most part, meiosis is very similar to mitosis. Gametes are the sperm and egg. Gametes in most organisms are referred to as the sperm (for males) and the egg (for females). During fertilisation they join to form a zygote, which then divides by mitosis to produce more ... WebNov 20, 2024 · Meiosis and mitosis both have a prophase, metaphase, anaphase, telophase and cytokinesis. In meiosis, prophase, metaphase, anaphase and telophase occur twice. The first round of division is special, but the second round is more like mitosis. In mitosis, prophase, metaphase, anaphase and telophase occur once. Prophase. WebMar 29, 2011 · Mitosis is the type of cell division that occurs in the vegetative cells of the organism while meiosis occurs in the reproductive cells of the organism. Some of the specific processes and products of meiosis differ from that of mitosis.
