“…This idea is supported by the close match between the variability of the cone ratios of parasol ganglion cells and H1 cells (Fig. 4) and by the substantial individual variability in the peak wavelength of the photopic luminosity function (Lutze et al, 1990). It predicts that the L/(L ϩ M) ratios of parasol ganglion cells and psychophysical measures that depend on luminosity (Cavanagh and Anstis, 1991) will covary.…”

“…Are genetic factors involved in the determination of the L:M cone ratio? Data from 52 observers from five families suggested that the transmission of L:M cone ratio was a result of allelic variation at a single gene locus [21]. However, the gene has not been identified yet.…”

“…35). On the one side are experiments involving Rayleigh matching in which the distribution of matches made by trichromatic subjects is multimodal (36)(37)(38); in other experiments, however, the match distribution is found not to be multimodal (39,40). The interpretational difference between these two sets of experiments is whether or not the match variations of normal human subjects can be considered to reflect an additional polymorphism of the human M and L photopigments.…”

The past 15 years have brought much progress in our understanding of several basic features of primate color vision. There has been particular success in cataloging the spectral properties of the cone photopigments found in retinas of a number of primate species and in elucidating the relationship between cone opsin genes and their photopigment products. Direct studies of color vision show that there are several modal patterns of color vision among groupings of primates: (i) Old World monkeys, apes, and humans all enjoy trichromatic color vision, although the former two groups do not seem prone to the polymorphic variations in color vision that are characteristic of people; (ii) most species of New World monkeys are highly polymorphic, with individual animals having any of several types of dichromatic or trichromatic color vision; (iii) less is known about color vision in prosimians, but evidence suggests that at least some diurnal species have dichromatic color vision; and (iv) some nocturnal primates may lack color vision completely. In many cases the photopigments and photopigment gene arrangements underlying these patterns have been revealed and, as a result, hints are emerging about the evolution of color vision among the primates.The generalization that color vision is a more developed and acute capacity in primates than it is in other mammals came from a consideration of the natural history of mammals (1). There is now extensive experimental support for this proposition (2), but a surprise from the results of color-vision studies of the past two decades is that primate color vision is not monolithic. The substantial variations in color vision that have been revealed, both among the members of some species of primate and between various groupings of species, have provided the opportunity to examine in greater detail the biological mechanisms that underlie color vision, particularly the photopigments of cone photoreceptors and the genes crucial for the production of these photopigments. These findings also provide leads about the evolution of primate color vision, and they have served to reawaken interest in understanding the functional utility of color vision. Cone Photopigment PolymorphismThe biological process that results in color vision is initiated by the neural comparison of signals from classes of cone photoreceptor that contain spectrally distinct photopigments. Among other things, the nature of the color vision that ensues depends on the number of such classes of photopigment, the spectral separation of the photopigments, and the relative representation of the different pigments among the population of photoreceptors.
