Genotype of a man with hemophilia = ![X^hY](https://tex.z-dn.net/?f=X%5EhY)
Crossing the two in marriage:
x ![X^hY](https://tex.z-dn.net/?f=X%5EhY)
Progeny: ![X^HX^h, X^HY, X^HX^h, and X^HY](https://tex.z-dn.net/?f=X%5EHX%5Eh%2C%20X%5EHY%2C%20X%5EHX%5Eh%2C%20and%20X%5EHY)
<em>The two sons from the cross have the genotype </em>
<em> and are therefore free from hemophilia.</em>
Hence, the percentage of their sons that will have hemophilia is zero (0).
