The Hardy-Weinberg principle states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of evolutionary influences (like mutation, selection, gene flow, genetic drift, and non-random mating). It describes a theoretical, non-evolving population (genetic equilibrium) and provides a mathematical baseline (p2 + 2pq + q2 = 1) to measure evolutionary change.
