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 sperm and an egg join in fertilization, the two haploid sets of chromosomes form a … WebProphase (from Ancient Greek προ-() 'before', and φάσις (phásis) 'appearance') is the first stage of cell division in both mitosis and meiosis.Beginning after interphase, DNA has already been replicated …
