Question

A person suffering from Klinefelter syndrome will have how many barr bodies?

• A. 2
• B. 3
• C. 1
• D. All of the above

Answer 1

Answer: (D)

All of the above

Klinefelter syndrome is the condition when a male is having one or more extra X chromosomes. Human males have one Y and one X chromosome (XY). A male with Klinefelter's syndrome has a sex chromosome arrangement of XXY/XXXY or XXXXY. The inactive X-chromosome in the somatic cell of a female is referred to as the Barr body. Its number is always one less than the total number of X-chromosomes in the cell, thus normal males do not have Barr body. But a person suffering from Klinefelter syndrome will have 1/2/3 Barr bodies depending on the number of X-chromosomes in the cells.

So, the correct answer is option D.
