sci.hardy-weinberg-allele-freq Calculator
Calculates allele and genotype frequencies from the Hardy-Weinberg equation p² + 2pq + q² = 1 and tests for equilibrium departure. If a recessive disease has carrier frequency 2pq = 1/50, then q ≈ 0.01 and disease frequency q² ≈ 1/10,000 — Hardy-Weinberg assumes random mating, infinite population, no selection.
Inputs
