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.
Why are Barr bodies not found in most human cells?
Barr bodies are inactivated X chromosomes found in female mammals as a mechanism to equalize gene dosage between males (XY) and females (XX). In most human cells, only one X chromosome is active, while the other is condensed into a Barr body, typically occurring in somatic cells of females. In males, since there is only one X chromosome, Barr bodies are absent. Therefore, Barr bodies are primarily found in the cells of females, and not in most human cells overall, especially in male cells.
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.
What is the Number of Barr bodies inside cheek cell of male with Klinefelter's Syndrome?
A male with Klinefelter's Syndrome (XXY genotype) would have two Barr bodies in each cheek cell, as they have an extra X chromosome. This extra X chromosome forms Barr bodies inactivated during embryonic development, leading to the presence of two Barr bodies in cells with two X chromosomes.
Where can barr bodies be found?

A Barr body is normally found in the nucleus of which kind of human cell?
A Barr body is normally found in the nucleus of female human cells. It is an inactivated X chromosome, which compensates for the presence of two X chromosomes in females by silencing one of them to achieve dosage compensation.
Does an individual with Turner syndrome have any Barr bodies present in their cells?
Individuals with Turner syndrome typically have only one X chromosome, so they do not have Barr bodies present in their cells. Barr bodies are inactive X chromosomes that are typically found in cells with two X chromosomes.
