(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.
1 During meiosis one cell divides twice to form four daughter cells. 2  These four daughter cells only have half the number of chromosomes of the parent cell â they are haploid. 3  Meiosis produces our sex cells or gametes (eggs in females and sperm in males).
