Corn Snake Genetics: Students Learn about the Fundamentals of Mendelism by Studying Corn Snakes
King, Kristin
Science Teacher, v71 n1 p50-53 Jan 2004
In an attempt to generate student enthusiasm on the subject of genetics, the author developed a Punnett square activity centered on the genetics of corn snakes to teach students about Mendelism and genetic diversity. As they began the activity, however, some unexpected twists occurred that allowed for investigation into corn snake anatomy and behavior. Overall, this turn of events enhanced the study of genetics and provided student opportunities for independent research, laboratory investigations, and long-range data collection. The genetics activity expanded into lessons on active and passive immunity and how knowledge of venomous and nonvenomous snakes contributes to medical practices. Their discussions also involved careers in corn snake breeding and genetics. They discussed reptile (snake) anatomy, morphology, and taxonomy. They were able to incorporate a lab on endothermic/exothermic reactions in the ecosystem and how it applies to warm-blooded and cold-blooded animals as well as discuss where snakes lie in the hierarchy of the food chain. (Contains 2 figures and lists 4 online resources.)
