Evidence of a preferential inactivation of the paternally derived X chromosome in a 46,XX true hermaphrodite

Abstract
The pattern of inheritance of several X polymorphic markers is studied in the pedigree of a 46,XX true hermaphrodite. The results of the Xga, 12E7, and G6PD segregation analysis favour the hypothesis of a preferential inactivation of the paternally derived X chromosome.
