D)pleiotropy.
E)autosomy.

Question

Quizplus · Accepted Answer

Nondisjunction occurs when chromosomes fail to separate during meiosis, resulting in an abnormal number of chromosomes in the daughter cells. This can lead to conditions such as Down syndrome, Turner syndrome, and Klinefelter syndrome. Epistasis, pleiotropy, and autosomy refer to other types of genetic phenomena and are not relevant to this question. Disjunction is a term used to describe the normal separation of chromosomes during meiosis, and is not applicable to this scenario.
