Question

Red-green colored blindness in humans is the result of an X-linked gene. 2 parents with wild-type vision produce 2 daughters with wild-type color vision and a son that is color blind.
A) what's the probability that both daughters are carriers for the color-blind allele? B) if one of the daughters marries a man with wild-type vision, what is the chance of their having a colored blind son?

Explanation / Answer

Let Xc be the allele responsible for Red-green colored blindness in humans and X be the normal wild type vision allele.

Genotype of wild type vision mother is XXc.

Genotype of wild type vision father is XY.

The gametes produced, genotypes of the children are represented in the Punnet
