The sea scallop - an inhabitant of waters off the Atlantic coast - is a striking example of genetic variation in nature. Though the shape of the shell is uniform, markings and color in this single species vary widely. Selective breeding for desirable traits (e.g., better flesh color or larger size) is one of the goals of artificial cultivation.
