Hardy-Weinberg equation is used calculate the frequency of occurrence of alleles in a population by using its equation $p^2+2pq+q^2=1$, where p is the frequency of occurrence of the dominant allele and q, that of the recessive allele. The Hardy–Weinberg principle, also known as the Hardy–Weinberg equilibrium states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences.
