WebMeiosis starts with a diploid cell and produces four haploid cells. In animals, the starting diploid cell is usually called a germ cell and the surviving haploid cells become gametes ( sperm and ova ). (In animals, the female mitotic sequence produces only one ovum; the other three haploid cells become "polar bodies".)
