When the assumptions of the Hardy-Weinberg principle are broken, evolution occurs. Population genetics theory models how four primary mechanisms alter allele frequencies. 1. Mutation

Population geneticists use statistical metrics to quantify genetic diversity and assess how populations are partitioned. Heterosity an introduction to population genetics theory pdf

Not all traits are controlled by a single gene (monogenic). Most visible traits, like height or skin pigmentation, are (controlled by many genes) and influenced by the environment. Quantitative genetics uses statistical methods (like variance and covariance) to analyze these continuous traits and calculate heritability , which predicts how a phenotypic trait will respond to selection. The Neutral Theory of Molecular Evolution The Impact of Population Structure

Several models have been developed to describe the behavior of genetic variation in populations:

Understanding how variation is structured is key. It helps determine if a population is genetically uniform or diverse. The Impact of Population Structure
