Definitions:

Deleterious Allele

A version of a gene that, due to mutation, can result in a lower chance of survival or reproduction for an organism that carries it.

Mutation-Selection Balance

An equilibrium state between the introduction of new genetic mutations and the removal of maladaptive ones by natural selection.

Equilibrium Frequency

A stable frequency at which a genetic allele is maintained within a population without the influence of external forces, typically as a result of evolutionary pressures.

Phenotype

Phenotype is an observable, measurable characteristic of an organism. A phenotype may be a morphological structure (for example, antlers, muscles), a developmental process (for example, learning), a physiological process or performance trait (for example, running speed), or a behavior (for example, mating display). Phenotypes can even be the molecules produced by genes (for example, hemoglobin). Genes interact with other genes and with the environment during the development of the phenotype.
