In humans color vision depends on genes encoding three pigments.The R (red pigment) and G (green pigment) genes are on the Xchromosome, whereas the B (blue pigment) gene is autosomal. Amutation in anyone of these genes can cause colour blindness.Suppose that a color-blind man married a woman with normal colorvision. All their sons were color blind, and all theirdaughters were normal. Specify the genotypes of both parents andall possible children, explaining your reasoning.
