Explore the controls that determine which genes are expressed at a given time, where in the body, and to what extent. Controls that act over and above the information in DNA are called epigenetic, and they can be passed on to offspring for a generation or two. Consider the case of honeybees, where a special food affects which genes are expressed, turning an ordinary larva into a queen bee.
