Allele Frequency Calculator
Estimates the frequency of a gene variant in a population using the Hardy-Weinberg equation.
Allele Frequency Calculator gives you a faster way to work through practical calculation scenarios without rebuilding the same calculation from scratch every time. Start with Frequency of Allele A (p) and use the live outputs to estimate Genotype Frequency of AA (p^2), Frequency of Allele a (q), and Genotype Frequency of Aa (2pq) in one pass. This page is built to help you compare scenarios quickly, validate rough assumptions, and move into a related calculator when you need a second angle on the same problem.
Use The Calculator In A Few Steps
Work through the inputs deliberately, then compare outputs instead of relying on a single scenario.
Scenario Checks
Use these examples to verify the behavior of the calculator before you run your own values.
