Frequency-Dependent Selection

Natural selection in which a trait’s adaptive value depends on its frequency among members of a population.

Recessive Allele

An allele that produces its characteristic phenotype only when its paired allele is identical, often masked by a dominant allele in a heterozygote.

Dominant Allele

An allele that expresses its phenotype even in the presence of a recessive allele within a diploid organism.
