Question

The term meiotic ______________ refers to the failure of chromosomes to separate normally during meiosis. This results in haploid cells that have too many or too few chromosomes.

a) Disjunction.

b) Synapsis.

c) Crossing-over.

d) Segregation.

Answer 1

Nondisjunction is the failure of chromosomes to separate normally during meiosis, resulting in haploid cells with an abnormal number of chromosomes.

Step-by-step explanation:

Nondisjunction is the failure of homologous chromosomes to separate during meiosis I or the failure of sister chromatids to separate during meiosis II, leading to the formation of n+1/n-1/n chromosomes. This results in aneuploid gametes, which are haploid cells that have too many or too few chromosomes.
