Question

A woman without hemophilia marries a man with hemophilia they have a daughter with hemophilia what is the genotype of the mother and father

Answer 1

Mother- XXH

Father- XHY

Step-by-step explanation:

The mother is a carrier for hemophilia and since the disease is sex linked and found on the X chromosome, only one of the alleles has that H allele attached to it. The father is male so he only has one X chromosome, which is why he is effected by the disease and not just a carrier like the mother.
