How does natural selection change allele frequencies?
... Negative frequency dependence: where I’m my own worst enemy Here the fitnesses of the genotypes (not just the marginal fitnesses of the alleles) depend on their own frequencies. In this made-up example, the fitness of the heterozygote is always half way between those of the homozygotes, so there’s ...
