What are the chances of future children having haemophilia?
Having one son with haemophilia does not decrease or increase the chance of having another. Regardless of how many children parents have, if the mother is a carrier of haemophilia any sons that she has will have a 50% chance of inheriting the disorder and daughters have a 50% chance of being a carrier. For someone with haemophilia their sons will not have haemophilia but all of their daughters will be carriers (click here for more information).
