Summary of Hardy-Weinberg equilibrium
Hardy-Weinberg equilibrium is a principle that states that allele and genotype frequencies in a population remain constant over generations unless disturbed by evolutionary influences - non-random mating, mutations, natural selection, limited population size, random genetic drift, gene flow. When the conditions for Hardy-Weinberg Equilibrium are met, allele frequencies can be determined by the equation: p + q = 1, where p and q give the frequency of specific alleles in the population. Genotype frequencies can also be determined by p2 + 2pq + q2 = 1, where p2 gives proportion of homozygous dominant genotype, 2pq gives proportion of heterozygous genotype, and q2 gives proportion of homozygous recessive genotype in the population.
Flashcards on Hardy-Weinberg equilibrium
Genetic is a factor in Hardy-Weinberg equilibrium, and describes changes in allele frequencies in a population over generations due to random chance.
