The hardy-Weinberg equation is a mathematical expression that is used to determine the genetic variation of a population at equilibrium. The mathematical expression expresses Hardy-Weinberg law, which states that allele and genotype frequencies in a population will remain the same from generation to generation if evolutionary events do not happen.
Mathematical, Hardy-Weinberg equation states that P2 + 2Pq + q^2 = 1, for two Allele A and a.
