WebMeiosis is the process of cell division used for sexual reproduction in eukaryotes. The chromosomes in the cell are cut in half and then combine with a haploid from the other parent. The cells produced by meiosis are usually diploid again. WebTo put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm and eggs. When a … WebJul 17, 2024 · There are two stages or phases of meiosis: meiosis I and meiosis II.

WebTypes of sexual life cycles. Sexual life cycles involve an alternation between meiosis and fertilization. Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells (gametes) fuse to form a diploid zygote.
