Hardy-Weinberg Calculator
Start from whatever you know about a population and get all five Hardy-Weinberg frequencies, with the working. Enter genotype counts and it also runs a chi-squared test of whether the population fits equilibrium.
What you can do
- Start from q², the dominant phenotype, p, q, 2pq or a 1 in N rate
- Count alleles directly from genotype counts and test the fit with chi-squared
- Shows p, q, p², 2pq and q² together, and carriers as 1 in N
- Plots heterozygote frequency against q
- Practice questions with worked answers
