Why don't males have Barr bodies?
Both Male and Female have the barr body, but in different chromosones. The above statement is INCORRECT. Barr bodies are formed mainly in females due to females having two X chromosomes while males normally have only one X chromosome (and a Y chromosome). The Barr body is formed from the inactive X chromosome. Males can sometimes be born with a mutation of having too many X chromosomes, in which case Barr Bodies would also be found in those specific males which typically causes Klinefelter's Syndrome.
What is X- inactivation?
Sounds like you are speaking of Barr bodies. In the somatic cells of women you have two XX chromosomes. If both these chromosomes were allowed to express gene product you would have big problems with too many proteins doing, or trying to do the same job. So, randomly from cell to cell, these superfluous chromosomes are methylated and inactivated so only one X is expressed somaticly in women.
How many sex chromosomes are there in each body cell?
Two. XX in females ( though one X is a Barr body and shut down by heavy methylation ) and XY in males.
