Question

In the above-given image, which of the labelled part is a barr body?

• A. 1
• B. 2
• C. Both A and B
• D. None of the above

Answer 1

The correct option is A 1

Barr bodies are the inactivated sex chromosome that is found in the human somatic cell.

As human females contain 2 X chromosome in somatic cells, one is active and other is made inactive so that only a limited amount of genetic material is expressed in the given cell.

This inactivated X chromosome remains there as Barr body and the process of inactivation is known as lyonization.

So, the correct option is '1'
