What is the genotype of colorblind female and normal male?
Females that are X+X+ or X+Xc have normal color vision, while XcXc females are colorblind. Males that are X+Y have normal color vision, while XcY males are colorblind. To determine the inheritance of red-green colorblindness (or any other X-linked trait), the genotypes of the parents must be considered.
