Genetic Equilibrium, The Hardy-Weinhard Principle, and Natural Selection
With this simulation, students use a physical model to gain perception into the genetic processes involved when natural selection is functioning on a population in genetic equilibrium. By developing a basic understanding of the Hardy-Weinberg Principle and associated equations, students can more easily grasp an understanding of the actual complexity of natural selection in nature.

•The principles of genetic equilibrium and natural selection relate to the process of evolution.
•The Hardy-Weinberg equations can be corroborated with data collected from a physical simulation.
•Allele frequencies in equilibrium will remain in equilibrium in the absence of mutation, migration, or selection.
•Natural selection operates against the less favorable phenotypes in a population resulting in a larger proportion of favorable phenotypes in subsequent generations.
