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.
Continuos Population Variation, controlled by multiple Loci, Phenotypes are measured in population, Phenotypic Traits are distributed over a range in the population. Simple Polygenic Inheritance. Two or more Loci lead to phenotype, no environmental influence on the phenotype, strictly genetic.
