WebApr 10, 2024 · In the first meiotic division, the homologous chromosomes separate daughter cells by the spindle apparatus. Then, the cells proceed to a second division without the DNA replication intervening round. The sister chromatids thus segregate to form daughter cells producing a total of four haploid cells. 2. Who Discovered Meiosis? WebMeiosis I reduces the number of chromosome sets from two to one. The genetic information is also mixed during this division to create unique recombinant chromosomes. Meiosis II, in which the second round of meiotic division takes place in a way that is similar to mitosis, includes all of the stages of division again. These stages have specific ...
