Which of the following is not an example of aneuploidy?
Show Hint
Phenylketonuria is a genetic disorder, not a chromosomal abnormality.

- Turner’s syndrome
- Down’s syndrome
- Phenylketonuria
Klinefelter’s syndrome
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Aneuploidy refers to the presence of an abnormal number of chromosomes. Turner’s, Down’s, and Klinefelter’s syndromes are caused by chromosomal number abnormalities. Phenylketonuria, however, is a metabolic disorder caused by a mutation in a single gene and not by aneuploidy.
