WebMeiosis. Meiosis describes the process of cell division for reproductive cells that will result in sperm or egg cells with half the number of chromosomes. This is in contrast to the cell division that takes place in nongerm cells called mitosis, which results in daughter cells that are identical. Figure 1 represents meiosis in females and males.
