The Hardy-Weinberg equation can help to estimate allele frequencies in a population. Dominant (p) and recessive (q) allele frequencies and genotype frequencies can be calculated using the equation p² + 2pq + q² = 1.
Course: AP®︎/College Biology > Unit 7. Lesson 4: Hardy-Weinberg equilibrium. Allele frequency. Allele frequency & the gene pool. Hardy-Weinberg equation. Applying the Hardy-Weinberg equation. Discussions of conditions for Hardy-Weinberg. Mechanisms of evolution.
The Hardy-Weinberg equation assumes stable allele frequencies in a population. Key conditions include no mutation, random mating, no gene flow, infinite population size, and no selection. Diploid organisms with sexual reproduction are also assumed.

The Hardy-Weinberg equilibrium is a principle that helps to predict allele frequencies in a population. It assumes no selection, no mutation, no geneflow, random mating, and large populations for stable allele frequencies.
