| Allele | one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome. |
| Genotype | the genetic constitution of an individual organism. |
| Phenotype | the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment. |
| Domiant | a dominant trait or gene. |
| Recessive | relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents, i.e., when not masked by a dominant characteristic inherited from one parent. |
| Incomplete | not having all the necessary or appropriate parts. |
| dominance | the phenomenon whereby, in an individual containing two allelic forms of a gene, one is expressed to the exclusion of the other. |
| Codominance | Codominance, as it relates to genetics, refers to a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual. |
| Punnett square | a graphic used to perdictc the results of genetic cross |
| Probability | Probability is simply how likely something is to happen |
