There is a 50% chance that daughters of a mother that is a hemophilia carrier will be carriers so we can assume that two of the daughters were carriers. In actuality, it could be more or it could be less. Women have two X chromosomes and pass one to their daughters. A female hemophilia carrier would have one normal X chromosome and one X chromosome with the hemophilia gene. Since one of these chromosomes would be passed to a daughter, there is a 50% chance that the daughter will be a carrier. Likewise, there is a 50% chance that a son will have hemophilia.Furienna said:I think so too. Olga, Tatiana, Maria and Anastacia probably were carriers. But no one knew, since it's hard to tell before they have children.
