Asexual reproduction is a form of reproduction in which the progeny, which arise from a single organism, only receive the genes of one parent. Only one parent has access to the entire gene pool of a child. Agamogenesis and asexual reproduction are interchangeable terms.

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 ). WebSexual life cycles involve an alternation between meiosis and fertilization. Meiosis is where a diploid cell gives rise to haploid cells, and fertilization is where two haploid cells … WebSince cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm).
