Interphase Ed Reschke/Getty … WebMar 24, 2011 · However, the primary function of meiosis is the reduction of the ploidy (number of chromosomes) of the gametes from diploid (2n, or two sets of 23 chromosomes) to haploid (1n or one set of 23 chromosomes). While parts of meiosis are similar to mitotic processes, the two systems of cellular division produce distinctly …
WebApr 9, 2024 · In Meiosis I, it is homologous chromosomes, which are synapsed at that time, that segregate and move apart. In rare cases, the sister chromatids (or paired chromosomes in Meiosis I) fail to separate, or dis-join. This failure to segregate properly is called nondisjunction and it can happen during mitosis, meiosis I, or meiosis II. WebThe process of meiosis happens in the male and female reproductive organs.
