The X and Y chromosomes are called sex chromosomes. The gene for hemophilia is carried on the X chromosome. Hemophilia is inherited in an X-linked recessive manner. Females inherit two X chromosomes, one from their mother and one from their father (XX). Males inherit an X chromosome from their mother and a Y chromosome from their father (XY).
She will, however, be a hemophilia carrier since she has the hemophilia gene on one of her X chromosomes. So in this case, all sons born to the couple will be normal and all daughters will be hemophilia carriers (Figure 2-4). Figure 2-4.Father with hemophilia; mother with normal blood clotting gene. All daughters of a man with hemophilia will be carriers (called obligate carriers). 2  If a carrier has a son, the son has a 50% chance of having hemophilia. 3  If a carrier has a daughter, the daughter has a 50% chance of being a carrier.
