Abstract
The term frequency dependence describes scenarios in which the likelihood
of an event occurring is strongly tied to how common a particular trait is.
Understanding frequency dependence is key to understanding numerous
biological processes relevant to evolution by natural selection, such as predation,
mimicry, disease, and effective vaccinations. We use dodgeball to demonstrate
frequency dependent selection in a hypothetical predator–prey community, and
provide possible extensions into other topics. This activity can be used with
biology students in high school through upper-level undergraduate courses.
