Explanation:
Detailed explanation-1: -So, the correct answer is ‘22 pairs + XXY male’.
Detailed explanation-2: -Aneuploidy occurs when the number of chromosomes a cell has doesn’t equal 46. While this can happen sometime during your lifetime, more often, it occurs when the number of chromosomes your child acquires from their biological parents doesn’t equal 46 due to an error in the creation of the egg or sperm.
Detailed explanation-3: -Aneuploidy refers to losses and/or gains of individual chromosomes from the normal chromosome set. The resulting gene dosage imbalance has a noticeable affect on the phenotype, as illustrated by aneuploid syndromes, including Down syndrome in humans, and by human solid tumor cells, which are highly aneuploid.
