Question

You have you are either a male or a female. What is nondisjunction? A) The failure of paired chromosomes to separate during cell division

B) The exchange of genetic material between homologous chromosomes
C) The formation of gametes during meiosis
D) The transfer of genetic information from parents to offspring

Answer 1

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 aneuploid gametes.

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 aneuploid gametes. Aneuploidy is a condition in which there is an abnormal number of chromosomes in the gametes, resulting in disorders such as Down syndrome or Turner syndrome. Nondisjunction can occur in either meiosis I or II, and the specific outcome depends on when and which chromosomes fail to separate.
