WebA cell containing 20 chromosomes (diploid) at the beginning of meiosis would, at its completion, produce cells containing how many chromosomes? Answer: 10 chromosomes (haploid) Karyotype A method of organizing the chromosomes of a cell in relation to number, size, and type. Fertilization The fusion of a sperm and egg to form a zygote. WebIn meiosis, however, you start with a diploid cell that divides twice to produce four haploid cells. In other words a diploid cell that has 2n chromosomes produces four cells, each of which contains n chromosomes. Now let's step back and talk briefly about chromosomes.

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".)
