WebApr 8, 2024 · Complete answer: Meiosis also induces genetic variation by means of the recombination process. Later, as two gametes combine during fertilization, this variation is increased even more, thereby producing offspring with special DNA combinations. WebMar 6, 2024 · It is the specific processes of meiosis, resulting in four unique haploid cells, that result in these many combinations. This independent assortment, in which the chromosome inherited from either the father or mother can sort into any gamete, produces the potential for tremendous genetic variation. citi credit card extended warranty appliances

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 ). WebAug 8, 2024 · Meiosis goes through all 4 phases of mitosis twice, with modified mechanisms that ultimately create haploid cells instead of diploid. One modification is in meiosis I.
