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

Answer 1

Aneuploidy is caused by nondisjunction

Step-by-step 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).

Answer 2

Nondisjunction in Meiosis

Step-by-step explanation:

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