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.

PCR Efficiency Calculator

Compute the amplification efficiency of a qPCR reaction from the slope of a standard curve fitting Cq values against the log of template concentration. A slope of −3.32 yields 100% efficiency (true doubling per cycle).
