Which of the following genotypes is NOT a result of nondisjunction?

A) hermaphroditism

B) Kleinfelter\'s syndrome

C) Turner Syndrome

D) Trisomy 21

Solution

Answer: A: hemaphrodotism. It is not due to non disjunction in the genotype. There are several ways in which this condition occurs. The affected individual has both testicular and ovarian tissue.

Klinefelter syndrome is caused by nondisjunction due to aneuploidy

Turner’s syndrome genotype might have a nondisjunction in the father. Usually ther is loss of X chromosome

In trisomy, usually the nondisjunction is during maternal meiosis.
