How are meiosis ii and mitosis different
WebMitosis occurs in both, asexual and sexual reproduction, while meiosis is characteristic of only sexual reproduction. There is no crossing over in mitosis, only in meiotic division. At the end of the mitotic division, four daughter cells have 23 pairs of cloned chromosomes from the mother cell. WebThey are caused by nondisjunction, which occurs when pairs of homologous chromosomes or sister chromatids fail to separate during meiosis. The risk of nondisjunction increases with the age of the parents. Nondisjunction can occur during either meiosis I or II, with different results ( Figure 7.8 ).
