Hemophilia is a sex-linked recessive disorder that takes place in males more than in females as females have two X chromosomes so if one is affected other still able to make clotting factors but in males, there are only one x chromosome.
If a hemophilic man XhY marries with a carrier women XHXh then the chances of their son for normal blooding would be :
Gametes:
Male: Xh and Y
Female: XH and Xh
Then cross:
Xh Y
XH XHXh XHY
(carrier daughter) (normal son)
Xh XhXh XhY
(hemophilic daughter) (hemophilic son)
Thus, the chances of normal son is 50% among sons
