WebAbstract. The hypothesis that red-green "color blindness" is caused by alterations in the genes encoding red and green visual pigments has been tested and shown to be correct. Genomic DNA's from 25 males with various red-green color vision deficiencies were analyzed by Southern blot hybridization with the cloned red and green pigment genes as ... WebApr 26, 2024 · Primate color vision is based on two to three cone types in the retina, each expressing a different class of visual pigment, making them the only mammals that possess trichromacy. These pigment classes are the short wavelength-sensitive (SWS1) pigment and the long wavelength-sensitive (LWS) pigment, orthologues of the same pigments found …

Defects in the genes responsible for visual transduction often lead to congenital color vision deficits. Any abnormalities of the retina, optic nerve, optic tract, and visual cortex can cause defects in color vision.
