# Genetics Revision ## Genotype vs Phenotype **Genotype:** Refers to the exact pairing of alleles. * **Example:** * B = blue eyes * b = green eyes * Possible genotypes: BB, Bb, bb **Phenotype:** Refers to the exact expression of the trait. * **Example:** * There are only two possible phenotypes: * Blue eyes * Green eyes * **Note:** Phenotype only considers the expression of the trait, not the underlying allele pairing. For example, genotypes BB and Bb both result in the same phenotype (blue eyes).
