Web23 mei 2024 · Meiosis Definition. The general meiosis definition is cell division that results in four haploid cells (half the "normal" amount of DNA) from one mother cell. It's used for the creation of gametes like eggs, sperm and spores in some types of plants. The general steps of meiosis are: interphase (separated into G1, S, and G2 phases), prophase 1 ... 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 ). do both student and parent need to file fafsa creating new holiday traditions
