Problem: Color blindness is a sex linked recessive trait carried on the X chromosome. If a woman who is not colorblind and is a carrier (XBXb) marries a man who is color blind, what are the possible genotypes and phenotypes of their offspring? Use ratios and percentages.
Is it possible for the man to pass colorblindness to his daughters? It is possible for the man to pass colorblindness to his son?
