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.ene 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.
There are three main kinds of color blindness, based on photopigment defects in the three different kinds of cones that respond to blue, green, and red light. Red-green color blindness is the most common, followed by blue-yellow color blindness. A complete absence of color vision âtotal color blindness â is rare. Sometimes color blindness can be caused by physical or chemical damage to the eye, the optic nerve, or parts of the brain that process color information.
