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.

∙ 13y agoThis is Biology--it's not specific to humans. In species where the sex is determined by the presence of a Y chromosome (which includes most mammals, including humans) the females have two X chromosomes in each cell of the body and the males have one X and one Y chromosome. In order for the cell to work properly, there can be only one functioning X chromosome, so one or the other X chromosomes must be inactivated.
X-inactivation occurs early in the development of the embryo. Independently, each embryonic cell will randomly and irreversibly inactivate one of the two X chromosomes in its nucleus. Once an embryonic cell has inactivated one of its X chromosomes, all the cells derived from it will inactivate the same X chromosome. As the cells develop, the inactivated X chromosome is compacted into an inert bundle called a Barr body.
Since males have one X and one Y, no inactivation takes place, so there is, in general, no Barr body found in the nucleus of somatic cells in male mammals.

Where is a barr body found?
A Barr body is the inactivated X chromosome that is usually found in the nuclei of female somatic cells. It can also occur in males when there is an abnormality and the male is XXY instead of the normal XY, a condition known as Klinefelter's syndrome. In this case, the male somatic cells would also contain a Barr body. --- The Barr body is the highly-condensed chromatin structure taken up by an inctivated X chromosome. The number of Barr bodies equal the number of inactive chromosomes.
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.

How many Barr bodies cell does XXXY has?
A Barr body is an inactivated X chromosome. An XXXY cell would contain 1 Barr Body. Men have no Barr bodies, and women have 1.

Do people with Klinefelter's syndrome have an inactivated X chromosome or a bar body?
People with Klinefert´s syndrome have one barr body. Yes , the number of barr bodies in a cell is always equal to the number of X chromosomes minus one. For example in the XXY chromosome there is one Barr body
