Red-green color deficiency is a sex-linked condition, while blue-yellow color deficiency is not. This means that the genes responsible for red-green color deficiency are found on the X chromosome, which is why males are more likely to have this type of color deficiency since they only have one X chromosome, while females have two X chromosomes. Blue-yellow color deficiency is caused by different genes and does not show a clear sex-linked pattern.
