Unformatted text preview: the cell when there is just one of each kind of chromosome, or the &quot;n&quot; number of chromosomes. (Diploid is the 2n number of chromosomes.) The diploid number of chromosomes will be restored when two gametes (egg and sperm) unite in sexual fertilization. The Process of Meiosis - Details There are three important parts to meiosis: Prior to any cell division, chromosomes must undergo DNA duplication. To achieve the reduction in chromosome number and appropriate distribution of chromosomes, meiosis requires two divisions, called Meiosis I and Meiosis II. Pairing of and separating of the homologous chromosomes occurs in Meiosis I, reducing the chromosome number. Meiosis I Meiosis II Meiosis II separates the duplicated chromosomes. At the completion of the second division, four cells will typically be produced....
