A normal man and a heterozygous color blind "carrier" woman have a baby. If they have a girl, what is the probability that the girl will be colorblind. If they have a boy, what is the probability that the boy will be colorblind?
First of all, carriers do not show the effects in their phenotype, so she cannot be colorblind.
You can do a Punnett square to find your answer.
However, to save you some time, the probability is 50% in both cases.
