Definitions:

Directional Selection

A form of natural selection in which one extreme phenotype is favored over other phenotypes, causing allele frequencies to shift in one direction.

Stabilizing Selection

Stabilizing selection favors individuals in the middle of the distribution of phenotypes present in a population (for example, by acting against individuals at either extreme).

Overdominance

A genetic phenomenon where the heterozygote genotype has a higher fitness or survival advantage than either of the homozygote genotypes.

Underdominance

A genetic condition in which heterozygotes have lower fitness than either homozygote, leading to a tension between alleles that can result in decreased population stability.
