The diagram below shows how nondisjunction can take place during meiosis I if homologous chromosomes don't separate, and how this can lead to the production of aneuploid gametes (eggs or sperm): Meiosis II. Nondisjunction can also happen in meiosis II, with sister chromatids (instead of homologous chromosomes) failing to separate.

Anaphase I: Instead of chromatids splitting at the centromere, homologous chromosome pairs (now shuffled by crossing over) move along the spindle fibers to opposite poles. Telophase I: The cell pinches and divides. Meiosis II Prophase II: It is visibly obvious that replication has not occurred.

WebThe meiosis is a process of cell division by which the chromosomes are reduced from the diploid to the haploid number. It takes place in all sexually reproducing organisms.

WebMeiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells.
