WebThere are two types of cell division. Mitosis produces two identical diploid daughter cells. Meiosis produces four non-identical haploid gametes (sex cells). WebMeiosis contains two separate cell divisions, meaning that one parent cell can produce four gametes (eggs in females, sperm in males).

Webdiploid (2N) to haploid (N). Meiosis thus differs from the simple division we imagined above, by the occurrence of one additional division. It is during this division that chiasmata are established between homologous chromosomes. Because meiosis comprises 2 divisions, a zygote undergoing meiosis always yields 4 daughter cells. WebMeiosis 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. WebSince cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase. Meiosis I Before entering meiosis I, a cell must first … bank teller salary range
