The only difference between genetically modified crops and ordinary plants is that there are more genes that make them produce extra traits  As early as 1983, biologists already knew how to transplant foreign genes into the deoxyribonucleic acid of a plant through biotechnology in order to produce some new properties that could not be obtained by hybridization: herbicide resistance, resistance to plant viruses, resistance to certain pests, etc
The genes used for transplantation can come from any living organism: bacteria, viruses, insects, etc
A crop that transplants other life genes to produce additional characteristics
