Question

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

Answer 1

Answer:

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.
