If nondisjunction occurs in humans for sister chromatids of one chromosome during Meiosis II, will any normal gametes result? What chromosome number would each gamete have?

Non-disjunction occurs when sister chromatids fail to separate during meiosis 1 or II


This results in monosomy or trisomy where the cell has an extra or missing chromosome which leads to a variety of genetic disorders. Also, if a cell is missing one or more chromosomes, it is said to be aneuploid.
