Default Secret Behind Butterfly Mimicry Identified

http://www.nytimes.com/2011/08/16/sc...=1&ref=science

"A team of French and British biologists, led by Mathieu Joron of the National Museum of Natural History in Paris, has discovered the butterfly’s solution. It has locked together in a supergene a cluster of 18 genes involved in specifying the wing pattern. The supergene is inherited as a single unit, the biologists report in the current issue of Nature.

The different versions of the supergene coexist in a dominance hierarchy. If the mother and father have different wing patterns, the offspring will display the pattern of whichever version of the supergene is dominant."
