Web18 nov. 2024 · Meiosis describes the process of cell division by which gametes are made. In this process, we begin with a cell with double the normal amount of DNA, and end up with 4 non-identical haploid daughter gametes after two divisions.. There are six stages within each of the divisions, namely prophase, prometaphase, metaphase, anaphase, … Web21 aug. 2024 · Meiosis is the process of cell division in which the original diploid cell divides twice to produce a total of four haploid cells. Thus, formed haploid cells consisting of half number of chromosome as the original diploid cell gives rise to gametes (sperm or eggs) that, on fertilization, supports sexual reproduction and a new generation of a diploid …
