Hemophilia & Genetic Inheritance

How is hemophilia inherited?

• When the father has hemophilia but the mother does not, none of the sons will have hemophilia. All of the daughters will carry the hemophilia gene.
• Women who have the hemophilia gene are called carriers. They sometimes show signs of hemophilia, and they can pass it on to their children. For each child, there is a 50% chance that a son will have hemophilia and a 50% chance that a daughter will carry the gene.
