Selection on phenotype/behavior changes the underlying genetics (allele frequencies)

Selection on phenotype/behavior changes the underlying genetics (allele frequencies). Directional selection on allele frequency. FF has highest fitness SS has lowest fitness. Selections alters the allele frequency of the pop.
