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.
predicting and calculating phenotype & genotype ratios/probabilities Calculating phenotype ratios. 1. Make a Punnet, for one trait, by drawing a two-by-two block of squares. 2. Label the possible alleles from one parent across the top of the squares. The possible alleles from the other parent are labeled across the left side of the block.
