Summary: Transgenics allow scientists to develop organisms that express a novel trait not normally found in the species (including humans); for example, a type of rice known as golden rice has elevated levels of vitamin A. Scientists have also developed sunflowers that are resistant to mildew and cotton that resists insect damage. Possible transgenic combinations can be broken down generally into three categories: 1) plant-animal-human combinations; 2) animal-animal combinations; and 3) animal-human combinations.
