what chromosome is affected by color blindness
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.
