Non-genetic Engineering Method: Mutation Breeding

This method involves the exposing of organisms (plants or seeds) to mutagens, be it chemical mutagens or ionizing radiations. These mutagens will induce random changes in the DNA pattern of the organism. The progeny of these mutagenized and matured organisms are then assessed for novel traits. This method produces random effects and is prone to forming mutations that are injurious to human health.
