A daughter has hemophilia a recessive sex-linked what are the possible genotypes of her parents

If a female child has hemophilia it is possible that the mother is a carrier of the hemophilia gene and the father has hemophilia.

Explanation:

A daughter gets X chromosome from both her parents.It is generally seen in males.Hemophilia is generally recessive in females.They act as carriers of hemophilia. This occurs because they have a X chromosome that dominates the hemophilia affected gene that they inherit from any parent.But, if both the parents have faulty genes ,i.e the mother is the carrier of the gene and the father is hemophiliac, then the chances are the daughter has hemophilia too.
