title: Role of Barr bodies obtained from oral smears in the determination of sex.
abstract: Barr body is an inactivated X chromosome in the normal female somatic cell. Inactivation of these chromosomes is known as Lyonization. Lyonization has both genetic and clinical significance. Barr body can be easily identified with ordinary stains. It also helps in identifying the sex of an individual when used judiciously. A review is made on the lyonization of Barr body and its utility in sex determination.
