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.
Non Hereditary Color Blindness. Color blindness has been known to result from a number of causes: Shaken Baby Syndrome: This can cause retina and brain damage and therefore can cause color blindness in infants and children. The damage is permanent so the effects will be carried on into adult life. Trauma: Similar to above, accidents and other traumas can cause swelling in the visual processing center of the brain â the occipital lobe.
