Each cell contains one-half the number of chromosomes as the original parent cell. Meiosis is similar to the cell division process of non-sex cells known as mitosis. Mitosis produces two cells that are genetically identical to and contain the same number of chromosomes as the parent cell. These cells are diploid cells because they contain two sets of chromosomes. Human diploid cells contain two sets of 23 chromosomes for a total of 46 chromosomes. When sex cells unite during fertilization, the haploid cells become a diploid cell. The production of sperm cells is known as spermatogenesis. This process occurs continuously and takes place within the male testes.
