DNA Facts - Did you know?
Did you know that DNA is capable of perfect replication. Every time a cell divides, all the DNA in the cell must make an identical copy of itself.
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.
