Gene Expression Fold Change Calculator

Determine how much a gene is up- or down-regulated by dividing treatment expression by control expression. Used by researchers analyzing qPCR, RNA-seq, or microarray data to quantify gene activity changes.

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.
