For 10 points, name this process exemplified by the viceroy and monarch butterflies, in which one species attempts to appear as another.
Sheppard developed a scale to measure the evolutionary advantage of this process by plotting fitness against a color pattern. Two unpalatable species evolve similar patternings in the Mullerian type of this process. In the Batesian type, one less-harmful species adopts the look and behavior of a more-harmful species.
