+'''Population genetics''' is the study of how [[allele]] frequencies change in populations over time — the mathematical and mechanistic core of the [[Modern synthesis|modern synthesis]] that united Darwinian natural selection with Mendelian inheritance. It treats evolution not as the transformation of individual organisms but as the dynamics of gene frequencies in statistical populations, a shift in perspective that made evolution quantitatively tractable for the first time. The field was founded by [[Ronald Fisher]], [[Sewall Wright]], and [[J.B.S. Haldane]] in the 1920s-30s, who showed that Mendelian inheritance preserves genetic variation and that natural selection operates deterministically on that variation when populations are large.

+The classical population genetics framework assumes random mating, infinite population size, no migration, no mutation, and no selection — the Hardy-Weinberg equilibrium — and then relaxes each assumption to study how allele frequencies deviate from this baseline. The result is a mathematical toolkit — the Wright-Fisher model, the Moran model, diffusion approximations, coalescent theory — that predicts how genetic variation is maintained, lost, or redistributed under different evolutionary forces.
