evolution
answer bank
no migration
natural selection
no natural selection
genetic drift
migration
no mutation
no genetic drift
nonrandom mating
random mating
mutation

Explanation:

Hardy-Weinberg equilibrium requires conditions that prevent allele frequency changes: no migration (no gene flow), no natural selection (no differential survival/reproduction), no mutation (no new alleles), no genetic drift (large population size implied), and random mating (no preferential mating). Evolution occurs when these conditions are violated: natural selection (adaptive change), genetic drift (random allele changes), migration (gene flow), mutation (new alleles), and nonrandom mating (alters genotype frequencies).

Answer:

Hardy-Weinberg equilibrium: no migration, no natural selection, no mutation, no genetic drift, random mating
Evolution: natural selection, genetic drift, migration, mutation, nonrandom mating
