Definitions:

Stabilizing

A type of natural selection that favors the average individuals in a population, thereby maintaining the population's genetic variation.

Directional

In evolutionary biology, a type of natural selection that favors one extreme phenotype over others, causing a shift in the population's phenotypic distribution over time.

Additive Alleles

Alleles that contribute to the phenotype in a way that the effects of individual alleles add up to produce the overall phenotype.

Epistatic Alleles

Genetic alleles that mask the effect of alleles at other loci in determining phenotypic expression.
