Accidents during meiosis that can result in trisomies and monosomies are called
A) nondisjunctions.
B) inversions.
C) reciprocal translocations.
D) recombinations.
E) acrocentricities.

Question

Quizplus · Accepted Answer

Nondisjunctions occur when chromosomes fail to separate during meiosis, resulting in one gamete with an extra chromosome (trisomy) and another gamete missing a chromosome (monosomy). Inversions and reciprocal translocations involve changes to the structure of chromosomes, while recombinations refer to the exchange of genetic material between homologous chromosomes. Acrocentricities refer to the location of the centromere on a chromosome and are not relevant to accidents during meiosis.
