C)recombination.
D)unequal segregation.

Question

Quizplus · Accepted Answer

Nondisjunction is the meiotic error that results in aneuploid cells. It occurs when homologous chromosomes or sister chromatids fail to separate properly during meiosis, leading to the formation of gametes with an abnormal number of chromosomes. This can result in conditions such as Down syndrome, Turner syndrome, and Klinefelter syndrome. Crossing over, recombination, and unequal segregation can also lead to genetic variation, but they do not specifically result in aneuploidy.
