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 ). WebIn some species, cells enter a brief interphase, or interkinesis, before entering meiosis II.
