WebApr 13, 2024 · We can think of meiosis as a way cells very carefully count and divide their chromosomes so that each gamete, each egg or sperm, has exactly 23 chromosomes. Then when an egg with its 23 chromosomes is fertilized by a sperm with its 23 chromosomes, the resulting fertilized egg has exactly 46 chromosomes. WebThere are two types of cell division. Mitosis produces two identical diploid daughter cells. Meiosis produces four non-identical haploid gametes (sex cells).
