Hardy-Weinberg for an immune response

Built for engineers using it for real design work. Go from concept to a running model in the browser, then scale to the cloud when needed. Simulate an immune response live below — adjust the inputs and watch it respond, right in your browser.

Hardy-Weinberg & SelectionLive

Controls

Presets

Without selection, allele frequencies stay put and genotypes settle at p², 2pq, q² — Hardy-Weinberg equilibrium. Give the genotypes different fitness and selection shifts the allele frequency each generation. Heterozygote advantage (high Aa fitness) can hold both alleles in a stable balance.

Governing equation

Reading this result: Allele A is favored at every genotype, so directional selection drives p toward 1 and eventually fixes A.
