Meiosis occurs in diploid cells. The chromosomes duplicate once, and through two successive divisions, four haploid cells are produced, each with half the chromosome number of the parental cell. Meiosis occurs only in sexually reproducing organisms.
That is - meiosis only occurs in the gametes. ** The cells return to having the normal (called diploid) number of chromosomes after fertilization of the ova by the sperm. Meiosis consists of two successive divisions, each of which is divided into four phases. The first meiotic division is similar to mitosis (defined above) and the second meiotic division is the reduction stage. Meiosis enables the exchange of genetic material between chromosomes.
