(2001-9) The reduction of the chromosome number during meiosis is most important for: a. keeping the amount of DNA in the cell at a minimum level b. WebSummary. Meiosis is a type of cell division that starts with a diploid, 2 n cell. The process includes two chromosome divisions and produces four haploid, n cells. The haploid cells are genetically different from each other due to crossing over in Prophase I and independent assortment in Anaphase I.

During meiosis I, since homologous chromosomes are separated, ploidy falls to 2n (the original number) and then during meiosis II ploidy finally falls to n in the resulting daughter cells. Ploidy reduction does not occur in mitosis. WebEarly in the development of an animal embryo, special diploid cells, called germ cells, are made in the gonads (testes and ovaries).
