Selective Breeding

Selective breeding has been carried out for centuries to make animals bigger and crops more productive. Individual plants and animals with desired traits are bred to produce offspring with those traits.

Then what is genetic modification? It introduces genes from another species into the DNA of plants or animals that are then bred to produce offspring with desired traits.
