Natural Selection results in increase in one (or more) genotypes
... Soft Selection can promote multiple-niche polymorphisms. Frequency Dependent Selection Fitness depends on the frequency of a particular phenotype (genotype) in the population. Inverse frequency-dependent selection – The rarer a genotype is in the population, the greater its fitness. This process can ...
