Explanation:
A man with hemophilia (a recessive, sex-linked blood clotting disorder) has a daughter of normal phenotype. She marries a man who is normal for the trait.
XH - normal
Xh - hemophilia
Since this is a recessive disorder, one XH allele will give a normal phenotype. When the offspring do not have a XH and only have the Xh allele/alleles they will have the hemophilia condition.
Man's genotype is XhY.
Daughter's genotype is XHXh
