Nondisjunction Can Produce Gametes with 22 and 24 Chromosomes

Question

Nondisjunction can produce gametes with 22 and 24 chromosomes.

Accepted Answer

Nondisjunction is a failure of homologous chromosomes or sister chromatids to separate properly during cell division, resulting in gametes with an abnormal number of chromosomes. In this case, if nondisjunction occurs during meiosis I or II in a cell with 46 chromosomes, it can produce gametes with either 22 or 24 chromosomes.
