Is the haemophilia gene really recessive?
Yes, hemophilia is a X-linked recessive trait. I have NEVER heard anything to even question that, and it is often used as an example in biology books when teaching genealogy. It is shocking to me to see an “expert” say something to the contrary. However, your specialist is correct about it being possible for a female to have hemophilia, though it is rare. In order for that to happen a male with hemophilia and a female carrier would have to have a daughter and that daughter would have a 50% chance of having hemophilia. This is very rare, as in the US there is only even about 20,000 hemophiliacs. She is also correct about other doctors not knowing much about hemophilia. It is shocking some of the misconceptions that are out there.
