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.
Sexual reproduction is associated with the process of meiosis - a modified form of mitosis. Meiosis occurs only in diploid cells, and produces haploid progeny. The haploid (1N) products of meiosis are known as gametes. During meiosis, homologous chromosomes align with one another in a process known as synapsis.
