Color Blindness from Gene Mutations. Inherited color blindness is usually the result of receiving a genetically mutated gene on the X chromosome; however research has shown that mutations that can lead to color blindness originate from in excess of 19 different chromosomes and many different genes.n females, if one X chromosome is defective, the normal one will protect the woman from being color blind. Females who have a defective gene are carriers, their sons have a 50% chance of being color blind, and their daughters have a 50% chance of becoming a carrier.
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.
