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.
However, there is a 50% chance that a son will have inherited the gene and will express the trait or disorder. What are some of the different types of X-linked recessive conditions? Examples of X-linked recessive conditions include red-green color blindness and hemophilia A: Red-green color blindness. Red-green color blindness means that a person cannot distinguish shades of red and green (usually blue-green), but their ability to see is normal.
