Can nondisjunction occur in meiosis 1 and 2
WebIf nondisjunction occurs in meiosis II, two of the four products will be unaffected by the event and two of the products will be abnormal. One abnormal product will have an extra chromosome, and the other abnormal product will be missing that chromosome.

WebThe effects of nondisjunction in meiosis I are more far-reaching than that in meiosis II. This is because all four gametes that arise have altered number of chromosomes. In Meiosis II In this process, separation of sister chromatids in anaphase II fails, resulting in an uneven distribution of the chromatids into the newly formed daughter cells. WebAs in mitosis, the cell grows during G _1 1 phase, copies all of its chromosomes during S phase, and prepares for division during G _2 2 phase. During prophase I, differences …
