The most common type of red-green color perception defect is due to a mutation on the X-chromosome (i.e. a red-green color blind allele). X-linked red-color blindness is a recessive trait. Females heterozygous for this trait have normal vision.The color perception defect manifests itself in females only when it is inherited from both parents.oth X-chromosomes must carry the mutant allele for the females to be color blind. Red-green color blind females are homozygous for the recessive allele. Females with one mutant allele and one normal allele are heterozygous carriers.
Inherited color blindness is most common, affects both eyes, and does not worsen over time. This type is found in about 8% of males and 0.4% of females. These color problems are linked to the X chromosome and are almost always passed from a mother to her son. Color blindness may be partial (affecting only some colors), or complete (affecting all colors).
