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.
Red-green color blindness is a sex-linked trait. The receptors of red and green color are found on the X chromosome; therefore, men are more likely to be red-green color blind â¦ since they only have one.   Blue-yellow color blindness is found on chromosome 7, and is equally distributed between men and women.2 people found this useful.ost color blindness is caused by an inherited genetic defect where the functioning of the color receptive cones in the retina is deficient-or where the cones are absent alt â¦ ogether. It is most commonly inherited from mutations on the X chromosome.
