In humans, hemophilia is a sex-linked recessive trait. If a female who is a

A woman who is a carrier has: a 25% (one in four) chance of having a daughter who is a carrier. a 25% chance of having a son with hemophilia. and a 50% chance of having a child (boy or girl) who does not have the gene for hemophilia at all (Figure 2.5)
