NettetMeiosis 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 … NettetMeiosis consists of one round of DNA replication and two rounds of chromosome segregation. In meiosis, there are two steps: meiosis I and meiosis II. The differences between meiosis and mitosis are (1) homologous chromosomes pair at prophase of meiosis I; (2) genetic recombination, called meiotic crossing over, occurs regularly at …
