Hardy Weinberg Equilibrium

The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors. When mating is random in a large population with no disruptive circumstances, the law predicts that both genotype and allele frequencies will remain constant because they are in equilibrium.

In this activity, you will use a simulation to:
  1. Model a population in Hardy-Weinberg equilibrium.
  2. Determine the effect of the mechanisms of evolution and environmental changes on the genetic makeup of a population.
