If a woman has two X chromosomes, how do we know which X chromosome each of her offspring has? She received one X from her mother and one X from her father. Will her offspring receive the X from her mother or the X from her father? Is there a 50/50 chance of either? Or does it depend upon the offspring's sex- i.e. females receive X chromosome donated from grandmother, males receive X chromosome donated from grandfather? Do we know for sure?
