What must be the genotype?

Sonbull [250]

Answer:

XnY

Explanation:

II-2 is a male so the genotype must have a Y in it. Majority of the other options do not have Y, so they are incorrect. Because the individual is male, the father has passed a Y chromosome, while the mother has passed an X chromosome. The X chromosome is Xn because the mother is hemolytic, which is a recessive trait. So both the mother's X chromosomes carry the hemophilia trait.
