Mitosis and meiosis. Mitosis produces normal diploid (2n) somatic cells. Meiosis produces <br />haploid (n) germ cells that mature into gametes (eggs and sperm). An important feature of meiosis is that <br />homologous chromosomes form pairs that may cross over at the first metaphase. Chromosome number is <br />reduced from 2n to n after the first meiotic metaphase. (From Strickberger 1976.) <br />11
