The Hardy–Weinberg Equation Predicts Genotype Frequencies from Allele Frequencies

Definition

The Hardy–Weinberg principle

The Hardy–Weinberg principle is a mathematical model that predicts how allele and genotype frequencies remain constant in a population—unless evolutionary forces act upon it.

The Hardy–Weinberg equation predicts how alleles and genotypes are distributed in a population that is not evolving.
It uses two equations together: p + q = 1 and p² + 2pq + q² = 1.

What Each Term Means

p
1. Frequency of the dominant allele.
q
1. Frequency of the recessive allele.
p²
