Genetically modified crops. Genetically modified crops (GM crops, or biotech crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering techniques. In most cases the aim is to introduce a new trait to the plant which does not occur naturally in the species.
Genetic engineering (GE, aka Genetically Modified Organisms (GMO)) is the process of transferring specific traits, or genes, from one organism into a different plant or animal. The resulting organism is called transgenic or a GMO (genetically modified organism).very single decision a farmer or corporation makes about growing or raising a certain kind of food affects the final product.
