    This page has been archived and is no longer updated. Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring. Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division.

    NCBI Bookshelf. Cooper GM. The Cell: A Molecular Approach. Sunderland MA : Sinauer Associates; The somatic cell cycles discussed so far in this chapter result in diploid daughter cells with identical genetic complements. Meiosis, in contrast, is a specialized kind of cell cycle that reduces the chromosome number by half, resulting in the production of haploid daughter cells.

    Egg meets sperm

    Meiosis and the Formation of Eggs and Sperm March 1, Readings: Meiosis: Ch 9: p - , - , Figure 9. Just like everyone else Remember that is a typical diploid cell 2n , there are two copies of each chromosome. Homologous chromosomes , or homologues , are pairs of chromosomes identica l in size, shape, and for the most part gene sequence, that interact during meiosis.

    In humans, meiosis is the process by which sperm cells and egg cells are produced. In the male, meiosis takes place after puberty. Diploid cells within the testes undergo meiosis to produce haploid sperm cells with 23 chromosomes. A single diploid cell yields four haploid sperm cells through meiosis. In females, meiosis begins during the fetal stage when a series of diploid cells enter meiosis I.
