Describe a benefit of cloning plants and animals
What will be an ideal response?
Plant and animal food sources have been improved by artificial selection for thousands of years. Cloning is simply a type of artificial selection in which biotechnology makes it possible for organisms with desirable characteristics to be cloned in order to perpetuate those characteristics. Cloning has the potential to make food more healthful and less expensive as animals with desirable traits are cloned, and the clones are then used for breeding and further improvement of those characteristics.
