Nondisjunction results in gametes that produce either trisomy or monosomy in the cells of offspring.

Question

Quizplus · Accepted Answer

Nondisjunction occurs when chromosomes fail to separate properly during meiosis, resulting in gametes with an abnormal number of chromosomes. When these gametes combine with a normal gamete during fertilization, it can result in offspring with either an extra chromosome (trisomy) or a missing chromosome (monosomy) in their cells.
