Your friend found out that the soybeans her grandfather planted were genetically modified to be resistant to the herbicide Roundup. She wants to know what “genetically modified” means. You tell her that:
1.Scientists created the seeds for the soybeans and other genetically modified organisms in the laboratory.
2.Genetically modified organisms are produced by making changes to an organism’s DNA to produce a desired product such as pesticide resistance.
3.Genetic modification is a technical term that refers to the process of cross-breeding plants until the desired trait is achieved.
4.The entire genome of the soybean has been mapped, so her grandfather has chosen a variety that is resistant to the herbicide Roundup.
