1. Hemophilia is a sex-linked trait where X^H gives normal blood clotting and is dominant to the hemophilia allele X^h. Males that are X^HY are normal but males that are X^hY are hemophiliacs. For women: X^HX^H are normal
(unaffected); X^HX^h are normal but carry the allele (carriers); X^hX^h have hemophilia (are affected).
