Favorite Demonstration: An Interactive, Fiery Model of Genetic Complementation—Shedding Light on a Conceptually Difficult Biological Topic

Journal of College Science Teaching—September/October 1999

The phenomenon of complementation is not only one of the most important, but it is also one of the most challenging concepts for undergraduate genetics students to grasp. Complementation occurs when parents with the same mutant trait have offspring that are wild type, i.e., designated as the standard characteristic, for the trait. Using this demonstration as an analogy is valuable for both students and instructors since it easily illustrates for students the concept of complementation and promotes discussion of related topics in genetics.
