Web18 de dez. de 2016 · The stages of meiosis are divided into two parts, meiosis I and meiosis II. This is how meiosis creates haploid cells that can be used for sexual reproduction. When two of these cells combine, it will lead back to the original diploid cell with 2n and 2c. So, we’ve covered the general process of meiosis and how it is … WebMeiosis II is a mitotic division of each of the haploid cells produced in meiosis I. During prophase II, the chromosomes condense, and a new set of spindle fibers forms.

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 ). http://cyberbridge.mcb.harvard.edu/mitosis_6.html Web1.DNA content is halved only in meiosis I.
