Hardy-Weinberg Equation Expected Freq. Of Genotype + Expected Freq. Of Genotype + Expected Freq. Of Genotype = 1 P 2 + 2pq + q 2 = 1 C R C R + C R C W + q 2 = 1

Where it Happens  Bacterial communities  When looking for evolution  In populations w/ large gene pools

Hardy-Weinberg Equilibrium 1. No mutations 2. Random mating 3. No natural selection 4. Extremely Large population size 5. No gene flow
