DNA Facts - Did you know?
Every cell of human body contains DNA. Each DNA strand is almost two meters in length but is compressed into a space less than a tenth of a micrometer in length!
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.
