Question

Barr bodies are found ________________

(a) In the cytoplasm of female

(b) In the nuclei of female

(c) In the cytoplasm of male

(d) In the nuclei of male

I got this question in an online interview.

I'm obligated to ask this question of Dosage Compensation Mechanism for X linked Genes in chapter Chromosomes and Sex Determination of Cytogenetics

Answer 1

The correct answer is (b) In the nuclei of female

For explanation I would say: The inactivated X chromosome in female forms a highly condensed structure called the Barr body which is found in the nuclei. As male have only one X chromosome is no inactivation and no Barr body.
