One example of an X-linked trait is red-green colorblindness. Let (X^c) represent the recessive allele that causes colorblindness and (X⁺) represent the normal dominant allele. Females that are X⁺X⁺ or X⁺X^c have normal color vision, while X^cX^c females are colorblind. Males that are X⁺Y have normal color vision, while X^cY males are colorblind.
