Remember that males have an x and y chromosome, while women have two x chromosomes.

Explanation:

This means that a female offspring (daughter) inherits her father's only x chromosome and one of her mother's x chromosomes, while a male will receive his father's y chromosome and one of his mother's x chromosomes.  

This means that the boy will necessarily inherit his dad's Y chromosome, and any diseases that it carries.

Mother

Explanation:
