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.
