Nondisjunction:

Quizplus · Accepted Answer

Nondisjunction is a relatively common genetic occurrence in which chromosomes or chromatids fail to separate properly during meiosis, leading to an uneven distribution of genetic material among the resulting cells. It can occur in any chromosome, not just sex chromosomes, and can result in various outcomes, including Down syndrome or Turner syndrome, depending on which chromosome(s) is affected. It does not always result in nondevelopment of the zygote, as some outcomes may result in viable but abnormal offspring.
