Summary Introduction
To determine:
The reason for inactivation of X chromosome in the mammalian females.
Introduction:
Mammals are the vertebrate having mammary glands as one of their main characteristics which differentiate mammals from other groups. Mammalian females have developed mammary glands which are essential for the nourishment of the baby.
