Question:
Is it true that some males can only produce male offspring due to some abnormality of chromosomes?


Replies:
So far as I know, this doesn't occur naturally, but there are ways to inactivate the X or Y chromosome by genetic manipulation in the lab to produce males that only produce female offspring if the Y is inactivated or only males if the X chromosome is inactivated.
