The evolution of trichromatic color vision by opsin gene duplication in New World and Old World primates.
- BiologyGenome research
- 1999
The upstream region of this gene in a New World monkey, the marmoset, is sequenced to demonstrate the presence of an LCR in an equivalent position to that in Old World primates, and extensive homology from the coding region to the LCR with the upstream sequence of the human LW gene is shown.
Photopigments and colour vision in New World monkeys from the family Atelidae
- BiologyProceedings of the Royal Society of London. Series B: Biological Sciences

To determine whether closely related monkeys share this arrangement, spectral sensitivity functions that allow inferences about cone pigments were measured for 56 monkeys from two other Atelid genera, spider monkeys (Ateles) and woolly monkeys (Lagothrix).
Human Color Vision

Red-green color blindness is not associated with loss of acuity, although this is present in a rare form of dichromacy called Bornholm eye disease where cone dysfunction and myopia is also present, and the recessive disorder of achromatopsia where all cone classes may be absent.

The visual worlds of most primates are rich with potential color signals, and many representatives of the order have evolved the biological mechanisms that allow them to exploit these sources of…
Polymorphism of visual pigment genes in the muriqui (Primates, Atelidae)

The results affirm the existence of a single M/L cone opsin gene in the genus Brachyteles and discuss the implication of this result towards understanding the evolutionary ecology of trichromatic vision.
Phylogenetic analyses suggest independent origins for trichromatic color vision in apes and Old World monkeys
- BiologybioRxiv
- 2020
A phylogenetic tree is revealed that shows a clade containing all X-linked opsin paralogs found in Old World monkeys to be related to aClade containingall X- linked opsinParalogs identified in apes, suggesting that routine trichromacy originated independently in apes and Old World monkey.
CHAPTER 3 DID PRIMATE TRICHROMACY EVOLVE FOR FRUGIVORY OR FOLIVORY ?
- Biology
- 2005
The uniform trichromacy of Alouatta is known to have arisen separately from that of catarrhines, perhaps from a polymorphic arrangement similar to that seen in other platyrrhines.

The results indicate that the inheritance of color vision in the squirrel monkey can be explained by assuming that the three middle- to long-wavelength cone pigments are specified by three alleles at a single locus on the X chromosome.

Good quantitative agreement was found when the microspectrophoto-metrically measured absorbance spectra were used to predict the behavioural sensitivity of individual animals to long wavelengths and suggests that the behavioural variation arises from variation in the retinal photopigments.

The sister-group relationships of Brachyteles and Lagothrix, Saguinus and Leontopithecus, and Callimico with a Cebuella/Callithrix clade is not as well supported by the parsimony and bootstrap analyses and is not incorporated in the proposed cladistic classification.
Numbers and ratios of visual pigment genes for normal red-green color vision

It is revealed that many men with normal color vision have more pigment genes on the X chromosome than had previously been suggested and that many had more than one long-wave pigment gene.

The results suggest that PCE I and RCS I are functionally as well as structurally similar and that, despite marked differences in the fly and vertebrate visual systems, the transcriptional machinery involved in photoreceptor-specific gene expression has been strongly evolutionarily conserved.
