WebIn humans, body cells are diploid, containing 2 sets of chromosomes (one from each parent). In meiosis, DNA replication is followed by 2 rounds of cell division to produce 4 daughter cells, each with half the number of chromosomes as the original parent cell.

Web8 aug. 2024 · At the end of meiosis I, there will be 2 haploid daughter cells, one with n+1 and the other with n-1. Both of these daughter cells will then go on to divide once more in meiosis II, producing 4 daughter cells, 2 with n+1 and 2 with n-1. Nondisjunction in meiosis II results from the failure of the sister chromatids to separate during anaphase II. Web1 mrt. 2024 · Meiosis is then split into two phases: meiosis I and meiosis II.

WebMeiosis: Metaphase II In metaphase II the chromosomes are aligned at the center of the cell (Fig. 13). This time there are not homologous chromosomes to be paired with. This metaphase looks like metaphase of mitosis, but there is a key difference. What is the difference? (Compare metaphase of mitosis and metaphase of meiosis in Fig. 13). … WebIn meiosis II, the connected sister chromatids remaining in the haploid cells from meiosis I will be split to form four haploid cells.
