PLEASE I NEED HELP

A woman who is heterozygous for hemophilia marries a normal male. What are the possible phenotypes of their children?

Answer 1

Have you tried a Punnet Square yet?

but if not it would be:

HH: 25%

Hh: 50%

hh: 25%

Answer 2

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. Since this is a recessive disorder, one XH allele will give a normal phenotype.
