Red–green colour blindness is the most common single locus genetic disorder. Gene therapy is now used in adult monkeys, colour blind since birth, to provide the receptoral basis for trichromatic colour vision. Despite the expectation from classic visual deprivation experiments that neural connections established during development are incapable of processing an input not present from birth, treated monkeys displayed trichromatic colour vision behaviour.
