PHENOTYPE AND GENOTYPE. Definitions: phenotype is the constellation of observable traits; genotype is the genetic endowment of the individual. Phenotype = genotype + development (in a given environment). To consider these in the context of evolutionary biology, we want to know how these two are related.
Genotype vs. Phenotype. The genotype of an organism is the genetic code in its cells. This genetic constitution of an individual influences â but is not solely responsible for â many of its traits. The phenotype is the visible or expressed trait, such as hair color.
