Answer:

During embryonic development, female inactivates one of the X chromosomes because if both the X chromosomes are genetically expressed simultaneously, then double the necessary genetic products will be made. This inactivated X chromosome is called a Barr body. Men with Klinefelter syndrome (47, XXY ) have a single Barr body but it is not seen because that extra copy of X chromosome is inactivated.
