Interaction of just 2 genes governs coloration patterns in mice

Biologists at Harvard University and the University of California, San Diego, have found that a simple interaction between just two genes determines the patterns of fur coloration that camouflage mice against their background, protecting them from many predators. The work, published this week in the journal PLoS Biology, marks one of the few instances in which specific genetic changes have been linked to an organism's ability to survive in the wild.
