Question

The failure of homologous chromosomes to separate correctly during meiosis is called

Answer 1

Nondisjunction in Meiosis

Explanation:

Nondisjunction in Meiosis : Nondisjunction occurs when homologous chromosomes fail to separate during meiosis, resulting in an abnormal chromosome number

Answer 2

Answer:

Aneuploidy is caused by nondisjunction

Explanation:

Aneuploidy is caused by nondisjunction, which occurs when pairs of homologous chromosomes or sister chromatids fail to separate during meiosis. The loss of a single chromosome from a diploid genome is called monosomy (2n-1), while the gain of one chromosome is called trisomy (2n+1).
