A genetically modified organism (GMO) is an organism whose genetic material has been altered using genetic engineering techniques.Organisms that have been genetically modified include micro-organisms such as bacteria and yeast, insects, plants, fish, and mammals.GMOs are the source of genetically modified foods, and are also widely used in scientific research and to produce goods other than food. genetically modified organism (GMO) is an organism whose genetic material has been altered using genetic engineering techniques.
Other crops, which are labeled as monitored crops by the Non GMO project, can potentially become contaminated with GMOs by genetically modified relatives. Crops in this group include wheat, rice, flax, acorn squash, bok choy, turnips, rutabaga, Siberian kale, table beets and chard.he process of genetically altering a plant or animal involves the manipulation of its genetic material to create traits that cannot occur through traditional crossbreeding. GMOs are designed to have a number of desirable traits, including increased yield, defense against pests and drought tolerance.
