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.
Biologists use two fancy words to describe the relationship between your genes and your physical traits. The first word is genotype. Your genotype is your genes for a given trait. In most cases, you've got two copies of a gene - one from your mother and one from your father. The second word is phenotype. Phenotype is what you actually turn out to be, the way these genes get expressed. Biologists have a saying involving these two fancy words: Genotype determines phenotype..
