What is the Hardy-Weinberg principle?Show answer
The Hardy-Weinberg principle describes the allele and genotype frequencies expected in a population that is not evolving. It acts as a null model: if real frequencies match the prediction, no evolutionary force is acting on that gene; if they do not, something is changing the population.
What are forces that change allele frequencies?Show answer
Five processes can shift allele frequencies and so cause evolution:
