Definitions:

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.

Hardy-Weinberg Law

The Hardy-Weinberg Law is a principle that predicts the genetic variation and allele frequencies will remain constant in a population from generation to generation, assuming no evolutionary influences affect them.
