This teaching resource was developed by a K-12 science teacher in the American Physiological Society’s 2007 Frontiers in Physiology Program. For more information on this program, please visit www.frontiersinphys.org. The purpose of this simulation activity is to show how traits are passed from one generation to another. Students will simulate the development of four new traits for Betta splendens fish by simulating the repeated pairing of designer fish, created by students. Each new pairing will introduce one new trait for fin type or tail type or new color or level of aggression. The production of new generations will continue until the four new traits have been discovered over multiple generations. Prior to this activity, the students will have observed the agonistic behavior of a male Betta splendens fish when shown a picture of another male Betta splendens fish and then a mirror. Upon completion of this activity, students will be able to: show the mating pair with their new traits (phenotype), predict the F1 offspring of the new mating pair, and explain how the new traits affect the ability to survive, get a mate, and get food.
