Population Genetics — Hardy-Weinberg

Without evolution (no drift, selection, mutation, migration), allele frequencies p and q stay constant. H-W equilibrium: AA=p², Aa=2pq, aa=q². Add forces and watch allele frequencies change over generations.

Initial freq A (p) 0.50

Population size N 200

Selection s (A advantage) 0.00

Mutation μ (A→a) 0.000

Migration m (into pop) 0.000

Migrant freq p_m 0.80
