Hardy-Weinberg Equilibrium Calculator

A rigorous tool for computing allele and genotype frequencies in a non-evolving population based on the Hardy-Weinberg principle.

The 5 Assumptions

Hardy-Weinberg equilibrium relies on five strict assumptions. In nature, these are rarely met, which is why evolution occurs.

1. No mutations.
2. Random mating.
3. No gene flow (no migration).
4. Very large population size (no genetic drift).
5. No natural selection.
