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.
