Explanation:
If the infant inherits the father's X chromosome, she will be a female. The hemophilia gene will be present on the X chromosome from the father who has hemophilia. Her mother also gives the girl an X chromosome. The daughter will be a carrier if she inherits the normal X chromosome. She will have hemophilia if she inherits the X chromosome containing the hemophilia gene.
A guy with hemophilia and a woman who is a carrier has the same characteristics:
a 25% probability of having a son with hemophilia (one in four)
There's a 25% chance you'll have a son with normal blood clotting.
There's a 25% chance you'll have a carrier daughter.
There's a 25% chance you'll have a hemophiliac daughter.
