Definitions:

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.

Genotype

The genetic makeup of an organism that determines its specific traits, often in contrast to its observable characteristics (phenotype).

Esterase Production

Refers to the biological synthesis of esterases, enzymes that split esters into an acid and an alcohol in a chemical reaction with water.
