The genes for red and green color vision are located on the x chromosome. men inherit xy chromosomes, and women inherit xx chromosomes. red-green colorblindness is the most common colorblindness in humans, far more common than blue colorblindness. red-green colorblindness is caused by a recessive gene and disproportionately affects one gender more than another. which gender do you think is more affected by inheriting a mutated gene that causes red-green colorblindness? why do you think the recessive gene contributes to this effect?
