| Genotype | the entire genetic makeup of an organism also the combination of genes for one or more specific traits |
| Phenotype | an organism is appearance or other detectable characteristics |
| Dominant | in genetics describes an allele that is really expressed whenever the allele is present in an individual. |
| Recessive | describes an allele that will be masked unless the organism is homologous for the trait. |
| Incomplete Dominance | a condition in which two allles are expressed such the phenotype of a heterozygous induvidiual is an intermediate of the phenotypes of the two homogous parents. |
| Codominance | the condition in which two alleles are expressed such that the phenotype is a hetrozygos individual is a combination of phenotypes of the two homozygous parents |
