WebMeiosis produces our sex cells or gametes (eggs in females and sperm in males). Meiosis can be divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II): Meiosis I. 1. Interphase: The DNA in the cell is copied resulting in two identical full sets of chromosomes.
