|---|
| allele | One member of a pair or series of genes that occupy a specific position on a specific chromosome. |
| dominant | the trait that will be expressed in a hybrid |
| genetic engineering | The manipulating of genetic material in the laboratory. It includes isolating, copying and multiplying genes, |
| hybrid | a cross between parents of different genetic types or different species. |
| genotype | the genetic code for a trait |
| heterozygous | having two different alleles for a trait |
| homozygous | having identical alleles for a trait |
| incomplete dominance | when two different alleles together produce an intermediate (blended) phenotype |
| phenotype | The physical and/or biochemical characteristics of a person, an animal or other organism which are determined by their genetic makeup and/or environment |
| polygenic inheritance | when more than one set of alleles control a trait |
| heredity | the passing of traits from parent to offspring |
| Punnet Square | the chart used to determine possible genotypes of offspring |
| recessive sex-linked gene | abnormal gene on the X chromosome |
| genetics | the science of heredity |
