sidebarA. Genetic engineering (GE) is the modification of an organismâs genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species.hen gene transfer occurs, the resulting organism is called transgenic or a GMO (genetically modified organism). Genetic engineering is different from traditional cross breeding, where genes can only be exchanged between closely related species.
