The paternal X chromosome is always inactivated into a Barr body.

Explanation:

Marsupials also balance the number of X linked genes present in male and females by inactivation of one X chromosome in their females. Kangaroos and other marsupials exhibit inactivation of the paternal X chromosome. In marsupials, the paternal X chromosome is always inactivated and is present in the form of the Barr body in the cells of the females.
