The allele frequency of q (q^2 = Q) is calculated using the Hardy-Weinberg principle. Given Q = 0.3, the frequency of the q allele (q) can be found by taking the square root of Q, which is √0.3. However, the correct calculation involves considering both the homozygous (Q) and heterozygous (H) genotypes. Since q^2 = 0.3 (for QQ) and 2pq = H (where H = 0.4 and p + q = 1), we find q by solving for q in the equation q = q^2 + pq = 0.3 + (0.4/2) = 0.5.
