How many barr bodies are found in an extra y chromosome?
Barr bodies are inactivated X chromosomes found in females, and males typically do not have Barr bodies since they have one X and one Y chromosome. In the case of an individual with an extra Y chromosome (for example, XYY syndrome), there are no Barr bodies present, as Barr bodies are formed from X chromosomes only. Therefore, the presence of an extra Y chromosome does not contribute to Barr body formation.

What do the proteins in cell membrane do?
Many are active and passive transmember proteins for the passage of material into and out of the cell and some are markers on the cell surface that distinguish one bodies cells from another bodies cells.
How many barr bodies are present in a normal xx female?
A normal XX female will typically have one Barr body, which represents the inactivated X chromosome. The other X chromosome is active, while the inactive X chromosome condenses into a Barr body during development to compensate for gene dosage between males and females.
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.
