Hemophilia A is an X-linked recessive genetic disorder. The dominant allele for normal blood clotting is represented by HHH, and the recessive allele for hemophilia is represented by hhh.
The pedigree chart below shows the inheritance of hemophilia A in a family.
What is the probability that the unborn child (III-?) will be a male with hemophilia, and what is the probability that any daughter they have will carry the mutated allele (hhh)?
