Genotypes and phenotypes are related in that the genotype, which refers to an individual's genetic makeup or combination of genes, determines the phenotype, which refers to the physical characteristics or traits that are expressed as a result of those genes. In other words, the genotype codes for the traits that will be seen in the phenotype. For example, an individual with the genotype for blue eyes will have the phenotype of actually having blue eyes. The genotype acts as the blueprint for the phenotype.
