The gene affects color blindness, not the other way around. It is sex linked and recessive, males that are color blind have only one gene on the X chromosome, the Y chromosome is missing the like gene.A recessive gene on the X chromosome causes men to be color blind, a recessive gene on both the X and Y chromosomes causes females to be colorblind.This makes more men colorblind than women. And it is sex linked in that the woman contributes the X chromosome to the offspring. At least that is the way I remember it.olorblindness is a defective gene on the X chromosome. Females have 2 x chromosomes, thus one can serve as a backup for a defective gene. However, the Y chromosome in males is almost totally defective, thus does not have a backup.
