Quizplus · Accepted Answer

Hemophilia is an X-linked disorder, meaning it is carried on the X chromosome. Males only have one X chromosome (inherited from their mother) while females have two (inherited from both parents). Therefore, if a male with hemophilia were to have children, all of his sons would receive his Y chromosome and not his hemophilia-carrying X chromosome, so they would not have hemophilia. However, his daughters would have a 50% chance of inheriting the hemophilia-carrying X chromosome and becoming carriers.
