Definition Hardy Weinberg Principle- allele and genotype frequencies remain constant, are in equilibrium, for a given population over time, or through various generations. This is true unless there is a case of disturbance. In summary, the principle makes the following assumptions for a given population: 1. Large population size (large enough that sampling error is minimal) 2. No migration, no net movement (no genetic drift) 3. No mutations (no new alleles created or converted) 4. Random mating between individuals 5. Genotypes have equal fitness, no natural selection for a trait; all individuals have equal rates of survival and reproductive success

p 2 + 2pq + q 2 = 1 AND p+q=1 where p is frequency of the dominant allele and q is freq of recessive allele p 2 = percentage of homozygous dominant individuals, AA q 2 = percentage of homozygous recessive individuals,aa 2pq = percentage of heterozygous individuals , Aa
