Question

Quizplus · Accepted Answer

Since hemophilia is an X-linked recessive trait, a female offspring would need to inherit two copies of the hemophilia allele to express the condition. A carrier woman (X^HX^h) and a normal man (X^HY) will produce female offspring that are either carriers (X^HX^h) or normal (X^HX^H), but none will have hemophilia.
