Hardy-Weinberg Equilibrium Principle Or Theorem

Mathematical relationship that expresses, under theoretical conditions, the expected distribution of alleles among diploid genotypes in a population when allele frequencies do not change between generations; the central theorem of population genetics. The formula in a two allele case is: p2 2pq q2

1. Given certain allele frequencies, the relationship predicts genotype frequencies when a gene pool is static. Aka Castle-Hardy-Weinberg law.

See equilibrium.
