Abstract

People with normal color vision show interobserver variation in Rayleigh and red-green photometric matches, which may indicate variations in photopigment spectral sensitivities and receptor populations, respectively. We have previously shown that this variation is consistent with single-gene determination. The X-chromosome visualpigment genes are good candidate genes for determination of variation in these color-vision traits; however, other genes may also contribute to cone development and function, which affect these measures.
