Hardy Weinberg Expansion
Expand the Hardy-Weinberg equation.
p² + 2pq + q² = 1
Formula Explanation
Gives the frequencies of the three genotypes under equilibrium.
Variables Explained
p² = homozygous dominant; 2pq = heterozygous; q² = homozygous recessive.
Solved Example
If p = 0.6, q = 0.4, find genotype frequencies.
p²=0.36, 2pq=0.48, q²=0.16.
