1. 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. XH-normal. Xh-hemophilia. Since this is a recessive disorder, one XH allele will give a normal phenotype. When the offspring do not have a XH and only have the Xh allele/alleles they will have the hemophilia condition. Man's genotype is XhY. Daughter's genotype is XHXh (She got the Xh from her father.
The gene that causes hemophilia is often linked to a personâs sex. Males with the altered gene will have symptoms while females may or may not have symptoms. The chances of inheriting the gene also depend on which parent has the gene and if the child is male or female. There are 3 types of hemophilia: Hemophilia A: Caused by low levels of clotting factor VIII (clotting factor 8). This is the most common type of hemophilia. Hemophilia B: Caused by low levels of clotting factor IX (clotting factor 9).
