Hemophilia is a recessive X-linked trait. Jill Smith is not a hemophiliac but is a carrier. She marries John Jones who is a hemophiliac. What is Jill's genotype?

A man who has hemophilia and a woman who is a carrier have:
Since women have two X chromosomes, they can have genotype X X - if the female is a carrier but is still normal.
XX (normal female)
X X- (carrier female)
However it is very rare for a man with hemophilia and a woman who is a carrier to get together. That is why there have been only few girls born with hemophilia.
