| hybridization | In hybridization , breeders cross two genetically different individuals |
| clone | A clone is an organisms that has exactly the same genes as the organism form which it was produced |
| genetic engineering | In this process, called genetic engineering, genes from one organism are transferred into the DNA of another organism |
| gene therapygenome | This process, called gene therapy, will involve inserting copies of a gene directly into a persons cells. |
