Hardy-Weinberg equilibrium provides null model where allele and genotype frequencies remain constant across generations in absence of evolution, given by p2+2pq+q2=1. Assumptions include large random-mating population, no selection, mutation, migration or drift. Deviations indicate evolutionary forces at work. It allows estimating carrier frequencies for recessive diseases and testing if population is evolving. Therefore principle states Ideal populations remains stable under idealized conditions. This concept integrates genetics, ecology and molecular evidence, frequently tested in NEET, GATE and CSIR-NET, highlighting links between genotype, phenotype and environment.

Hardy-Weinberg equilibrium assumes infinitely large population size so sampling error becomes negligible across generations. Small population size violates this assumption, causing genetic drift where allele frequencies fluctuate randomly each generation due to limited gamete sampling forming zygotes. Drift leads to random loss or fixation of alleles, increased homozygosity, and deviation from p squared, two pq, q squared expectations. Thus small size acts as potent evolutionary force introducing stochasticity, unlike random mating or absence of mutation which are required conditions for stability at equilibrium.
