I assume you only need to determine the sex chromosomes.
The daughter has XX sex chromosomes. Since she has hemophilia, a recessive gene on the X chromosome, she must have inherited the hemophilia from both parents. However, since the son also receives an X chromosome from mom, it must be for normal blood clotting.
With this information, you should be able to figure the answer.
a couple has just learned that their daughter has hemophilia. they alredy have a son who does not have the disease.what are the genotypes of the couple
