Both Monosomy and Trisomy Result from Nondisjunction

Question

Both monosomy and trisomy result from nondisjunction.

Accepted Answer

Nondisjunction occurs when chromosomes fail to separate properly during cell division, resulting in an uneven distribution of chromosomes to the daughter cells. This can lead to the loss or gain of an entire chromosome, resulting in monosomy (one copy of a chromosome) or trisomy (three copies of a chromosome) conditions.
