Both calculators run independently — change the inputs on either side to compare results.

Hardy-Weinberg Equilibrium Calculator

Verify the Hardy-Weinberg equilibrium identity p² + 2pq + q² = 1 from two allele frequencies. Foundational population-genetics check that, in the absence of evolutionary forces, allele and genotype frequencies remain constant across generations.

Enzyme Activity Calculator

Compute enzyme activity in U/mL from the rate of absorbance change in a spectrophotometric assay using the Beer-Lambert law. One unit (U) is conventionally the amount of enzyme converting 1 µmol of substrate per minute.
