WebMitosis and meiosis both involve cells dividing to make new cells. This makes them both vital processes for the existence of living things that reproduce sexually.

WebSignificance of meiosis. Meiosis is the nuclear division of diploid cells into haploid cells, which is a necessary step in sexual reproduction; it is a significant chance to introduce genetic diversity into gametes.

WebApr 13, 2024 · Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm).
