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.
Red-green color blindness is an X-linked, recessive trait. In this problem set we will establish the pedigree of Audrei's family and see how the color perception defect is passed on from one generation to the next, but first let's look at a brief introduction to sex-linked inheritance.arbara, the mother of the seven children, has normal color vision, but Sidney, the father, has the red-green color perception defect. Audrei also has a half brother Stephan. Audrei and Stephan have the same mother, but a different father. Stephan is also red green color blind.
