Is colorblindness a non disjunction or a mutation

The most common cause of color blindness is confusion between red and green. It is a genetic mutation. Very few people are totally color blind (ie they see in black and white only) - most seem to have some color vision but get confused between certain colors. Oh, and for some strange genetic reason, far more men are color blind than women.

Colorblindness is caused by mutations in the genes. There are 3 color cones red, green and blue. when someone is colorblind there is usually a red or green cone missing.
