(See figure below, where meiosis I begins with a diploid (2 n = 4) cell and ends with two haploid (n = 2) cells.) In humans (2 n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23). Prophase I.
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.
