Convergent evolution of SWS2 opsin facilitates adaptive radiation of threespine stickleback into different light environments.
Repeated adaptation to a new environment often leads to convergent phenotypic changes whose underlying genetic mechanisms are rarely known.Here, we study adaptation of color vision in threespine stickleback during the repeated postglacial colonization of clearwater and blackwater lakes in the Haida Gwaii PINK EYE RELIEF archipelago.We use whole gen
