How do you do a punnett square that has blood properties?

Question

for example: normal blood: X^H hemophilia: X^h

A male that is dominant for blood properties produces offspring with a female that is heterozygous for blood properties. Produce a punett square and determine the genotypic and phenotypic ratios of their offspring.

Answer 1

If the male parent is dominant, that means he doesn't have hemophilia and is X^H Y.
The female is heterozygous, so she has two alleles that don't match: X^H X^h.

Parents: X^H X^h x X^H Y
Gametes for the left side of the Punnett square: X^H and H^h.
Gametes for the top of the Punnett square: X^H and Y.

Boxes inside the Punnett square would be ...
top row: X^H X^H X^H Y
second row: X^h X^H X^h Y

Genotypic ratio expected among offspring:
1 X^H X^H: 1 X^H Y: 1 X^h X^H: 1 X^h Y

Phenotypic ratio expected among offspring:
2 normal females: 1 normal male: 1 male with hemophilia
