Hemophilia is a sex-linked disorder carried on the X chromosome. A woman who is a carrier of hemophilia has the genotype X^H X^h also referred to as heterozygous for the trait. A man who has hemophilia is represented as X^h Y. A woman who is heterozygous for hemophilia marries a normal man. What will be the possible phenotypes of their children? How likely is it that their son will inherit the disease?
I got from a Punnett Square that they will all have hemophilia but I am not sure...I think I messed up somehow.
