These types of organisms are canned transgenic organisms. Transgenic organisms can be produced by putting one organisms DNA into the genes of another organisms. How do they do this?

Image shows how Transgenic animals are made. A gene is selected from the DNA of one animal and injected into the egg of another animal. The Egg is implanted into female and the offspring will express the selected gene.
