Why Are Only Females Carriers For Hemophilia

An Introduction To Hemophilia
Has no history of hemophilia. There are 3 reasons why this might happen: 1.It could be that hemophilia has been in the family for generations. Because no male showed signs of bleeding problems, no one knew hemophilia was present. The family may have had females who were hemophilia carriers. But if none of these women had sons, or none of their ... Read Content

(Assume 2 boys and 2 girls) Both boys will have the x-linked recessive disorder (100% of time will be YXr) and none of the girls will have it but will be carriers (100% of time will be XRXr). 17. ...

30% to 100% - Carrier Females. Because of lyonization of the x chromosome, the carriers of hemophilia A or B can be mildly affected themselves (30% factor level) or can be completely normal. Carrier females with bleeding are called . symptomatic carriers . and require life-long hemophilia follow-up. ... Read Full Source
