Gene pools and allele frequency change: mutation, selection pressures, genetic drift and founder effect, gene flow

What this note covers

1. Gene pools are measured through allele frequencies
2. Comparisons require matched populations and times
3. Mutation and selection pressures change pools differently
4. Genetic drift and founder effects are chance processes
5. Gene flow connects adjoining groups
6. Several mechanisms can explain one observed change
