About Hardy-Weinberg Equilibrium
The Hardy-Weinberg principle states that allele and genotype frequencies remain constant in a population across generations in the absence of evolutionary forces. The equation p² + 2pq + q² = 1 describes genotype frequencies, where p = dominant allele frequency and q = recessive allele frequency (p + q = 1).
