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.

Population Growth Rate Calculator

Compute the exponential growth rate r from initial and final population sizes over a time interval, as r = ln(N_final / N_initial) / t. Useful for bacterial cultures, microbial fermentation, cell-culture monitoring, and any closed system in exponential phase.
