| Individuals possessing the same genotype usually have the same phenotypic expression. | Individuals who look alike, i.e. have the same phenotype, may or may not have the same genotype. |
| The genotypic ratio obtained in the F2 generation of a monohybrid cross is 1 : 2: 1. | In the F2 generation of a monohybrid cross, the phenotypic ratio is 3: 1. |
