Interaction of just 2 genes governs coloration patterns in mice

...search has shown that such predators, all of which hunt by sight, will preferentially catch darker mice on the white sand beaches, providing a powerful opportunity for natural selection to evolve increased camouflage. Through a detailed genomic analysis, Hoekstra, Steiner, and Weber identified two pigme...
