Gene mutation on the X chromosome is most common and also explains why (depending on nationality) some 7% of males, but less than 1% of females exhibit color blindness of some form. Males only have one X chromosome, whereas females have two.
The gene for redâgreen color blindness is transmitted from a color blind male to all his daughters who are heterozygote carriers and are usually unaffected. In turn, a carrier woman has a fifty percent chance of passing on a mutated X chromosome region to each of her male offspring.olor blindness, or color vision deficiency, is the inability or decreased ability to see color, or perceive color differences, under normal lighting conditions. Color blindness affects a significant percentage of the population. There is no actual blindness but there is a deficiency of color vision.
