Hardy-Weinberg Distribution

  "term": "Hardy-Weinberg Distribution",
  "field": "Environment",
  "definition": "The ratio of genotype frequencies that evolve when mating is random and neither selection nor drift are operating. For two alleles (A and a) with frequencies p and q, there are three genotypes: AA, Aa, and aa. The Hardy-Weinberg ratio for the three is: p^2AA : 2pqAa : q^2aa. Deviation from this ratio indicates that some force is acting on the population (e.g., selection, mutation, migration, genetic drift, non-random mating).",
