| An allele that is masked when a dominant allele is present | Recessive |
| Having two identical alleles for a particular gene | Homozygous |
| having two different alleles for a particular gene | Heterozygous |

| A pattern of inheritance in which two alleles are neither dominant nor recessive; results in a blending of the two phenotypes | Incomplete Dominance |
| A pattern of inheritance in which two alleles are both dominant; results in both phenotypes being shown | Codominance |
