How are meiosis 1 and meiosis 2 different
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 ). WebMeiosis follows a similar pattern, but with two rounds of cell division. The first round, known as meiosis I, involves the separation of homologous chromosomes (chromosomes that are similar in shape and size). The second round, meiosis II, involves the separation of sister chromatids (copies of the chromosomes produced during DNA replication).

(2 points) Diploid cells have the full number of chromosomes but, haploid cells only have half the number of chromosomes. Diploid cells go into both mitosis and meiosis I, but haploid cells can only go into meiosis II.
WebMeiosis is the process by which replicated chromosomes undergo two nuclear divisions to produce four haploid cells, also called meiocytes (sperms and eggs). Diploid (2 n) organisms rely on meiosis to produce meiocytes, which have half the ploidy of the parents, for sexual reproduction. Halving the ploidy in meiocytes is essential for restoring ...
