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.
Males are more likely to be color blind than females as the genes responsible for the most common forms of color blindness are on the X chromosome. As females have two X chromosomes, a defect in one is typically compensated for by the other, while males only have one X chromosome. Color blindness can also result from physical or chemical damage to the eye, optic nerve, or parts of the brain.
