Hardy-Weinberg Equilibrium
Hardy-Weinberg Equilibrium states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. (The evolutionary influences are mentioned in the "5 Conditions of Hardy-Weinberg Equilibrium" tab. If the Hardy-Weinberg Equilibrium yields different allele or gene frequencies from one generation to the next, then evolution has occurred. Thus, it is commonly used to show that evolution is constantly occurring.
Note: in the AP biology test, you will know that you are answering a Hardy-Weinberg question because it will say something along the following lines:

- Assume the population is in Hardy-Weinberg Equilibrium
- Hardy-Weinberg Equilibrium is applicable
- etc.
