In humans, an XO individual has how many barr body in her cells
A. Four
B. One
C. Three
D. None of these
Answer: Option D
Solution(By Examveda Team)
In humans, an XO individual has no Barr body in her cells.A Barr body or X-chromatin is an inactive X chromosome in a cell with more than one X chromosome.
Someone with two X chromosomes (such as most human females) has only one Barr body per somatic cell, while someone with one X chromosome (such as most human males) has none.
Thus as an XO individual has only one X chromosome therefore there will not be any Barr body in its cells.
