If a male with hemophilia and a female who is homozygous dominant decide to have a child together, what percent chance is it that their child would have hemophilia?

Hemophilia is X-linked recessive. Father (affected) = XhY. Mother (homozygous dominant, unaffected) = XHXH.

Cross:
- Fathers' gametes: Xh or Y
- Mothers' gametes: XH only

Possible children:
- XH Xh = daughter, carrier (phenotypically normal)
- XH Y = son, normal

So 0% chance of an affected child. All daughters (100% of daughters) would be carriers; sons would be unaffected.
