KEY CONCEPT Hardy-Weinberg equilibrium provides a framework for understanding how populations evolve.

Hardy-Weinberg equilibrium describes populations that are not evolving. Biologists use models to study populations. Hardy-Weinberg equilibrium is a type of model.

Hardy-Weinberg equilibrium describes populations that are not evolving. Genotype frequencies stay the same if five conditions are met. very large population: no genetic drift no emigration or immigration: no gene flow no mutations: no new alleles added to gene pool random mating: no sexual selection no natural selection: all traits aid equally in survival

Hardy-Weinberg equilibrium describes populations that are not evolving. Real populations rarely meet all five conditions. Real population data is compared to a model. Models are used to studying how populations evolve.
