Abstract excerpt

The visual system plays a role in nearly every aspect of an organism's life history, and there is a direct link between visual pigment phenotypes and opsin genotypes. In previous studies of African cichlid fishes, we found evidence for positive selection among some opsins, with sequence variation greatest for opsins producing the shortest and longest wavelength visual pigments. In this study, we examined opsin...
