Summary Introduction
Introduction: Female mammal’s somatic cells consist of two X chromosomes that they inherit from their parents. Those two chromosomes are tightly condensed and thereby one of them will get inactivated. This condensed form of X chromosome is called as Barr body and the process of formation of Barr body is called as X chromosome inactivation. This is a normal process carried out in the body of female mammals to equalize the expression of the sex cells.
