Hemophilia in humans is a recessive sex-linked trait. A man with hemophilia and a woman who does not have hemophilia have a daughter who does not have hemophilia. She then marries a man who does not have hemophilia. What is the probability that their first child will be a daughter with hemophilia? A daughter without hemophilia? A son with hemophilia? A son without hemophilia? If the couple has four sons, what is the probability that all four will be born with hemophilia?

6. Hemophilia is a sex-linked trait. A person with hemophilia is lacking certain proteins that are necessary for normal blood clotting. Hemophilia is caused by a recessive allele so use "XH” for normal and "Xh" for hemophilia. Since hemophilia is sex-linked, remember a woman will have two alleles (XX) but a man will have only one allele (XY). A woman who is heterozygous (a carrier) for hemophilia marries a normal man: a. What are the genotypes of the parents? b....
