Hardy–Weinberg Calculator | Momchi's Genetics Tools™

Supports 2+ alleles. Enter allele labels and genotype counts or percentages. Computes allele frequencies, expected genotype frequencies, χ² test (accurate p-value)and charts. Export results.

This calculator computes allele frequencies, expected Hardy–Weinberg genotype proportions, and chi-square statistics for any number of alleles. Users enter genotype counts or percentages, and the tool automatically calculates allele frequencies, observed vs. expected genotypes, and statistical significance of deviation from HWE. Results are displayed in clean tables and a bar chart comparing observed and expected genotype distributions. It provides an intuitive, responsive interface suitable for teaching, research, and quick population-genetics analyses.
