Question

Quizplus · Accepted Answer

The Barr body is a condensed, inactive X chromosome found in the nuclei of somatic cells of females. It is formed during embryonic development as one of the two X chromosomes in females is randomly inactivated. Males do not have a Barr body as they only have one X chromosome. Option E is incorrect because the Barr body is formed from the X chromosome, not the Y chromosome.
