Hemophilia is a X-linked recessive trait. I will denote it as XA for dominant and Xa for recessive.
Hemophilic male: Xa Y
Carrier female: XA Xa
Cross:
Xa Y
XA XaXA XAY
Xa XaXa XaY
Thus, as shown, of the ratio of two possible female offspring genotypes for Hemophilia, only 1/2 will have the disease; the chance is therefore 50%.
The ratio for male offspring genotypes for Hemophilia is 1/2 as well; the chance is therefore 50%.
