Answer: XHXh (Note: the H's are superscripts.)
Explanation:
Hemophilia is a sex-linked recessive trait which means that the males having one altered copy of the gene is enough to cause the medical condition( as they have only one X chromosomes and females have two)

XhY is the genotype of father and son. As mother would be heterozygous because she is not affected, her genotype will be XHXh.
