How to Use the Hardy-Weinberg Equilibrium Calculator
Compute population genetics genotype distributions from allele frequencies:
Enter Dominant Frequency p
Input frequency of allele A (between 0.0 and 1.0).
Calculate Recessive q
Engine automatically computes q = 1 - p.
Enter Population Size
Input total population size N to convert percentages into individual counts.
View Genotype Distribution
Inspect p² (AA), 2pq (Aa), and q² (aa) percentages and sample counts.
Key Features & Population Genetics Principles
Strict Hardy-Weinberg Formula
Evaluates p² + 2pq + q² = 1 for two-allele locus equilibrium.
Population Individual Estimator
Projects exact numbers of homozygous and heterozygous individuals in any population size.

Population Genetics Guide: Hardy-Weinberg Equilibrium
The Hardy-Weinberg equilibrium is a fundamental concept in population genetics. It describes a non-evolving population in which allele frequencies do not change across generations under 5 key conditions: random mating, infinite population size, no natural selection, no genetic drift, and no mutation.
Frequently Asked Questions
