Hardy-Weinberg Problem Solving Steps

To solve Hardy-Weinberg problems step-by-step, start with the two core equations: p + q = 1 (allele

frequencies) and p² + 2pq + q² = 1 (genotype frequencies). Find the frequency of the homozygous

recessive genotype (\(q^{2}\)) from given data, take its square root to find \(q\),

then use \(p+q=1\) to find \(p\), and finally plug \(p\) and \(q\) into \(2pq\) to

find the heterozygotes, allowing you to solve for all allele and genotype frequencies in an ideal population.
