Haemophilia is recessive disease connected to the X chromosome.
Women have two X chromosomes. That is why only females with the recessive gene in both X chromosomes actually develop Haemophilia. If they carry only a single recessive gene then they become carriers (transmitters) of the disease.
In the case of men, it's different.Men have only one X chromosome and if they carry the recessive gene they will also develop the disease.
The Jewish population were well aware of this fact, and did not circumcise sons of women known to be carriers.
DNA Facts - Did you know?
DNA was eventually discovered by Friedrich Miescher in 1869. At that time however, scientists hadn't realized DNA held the genetic code to life until 1943. Up until then, the general belief was that proteins were responsible for holding genetic information.
