Types of GMOs. GMO varieties exist for crops such as alfalfa, canola, corn, cotton, papaya, rice, soybean, sugar beet, summer squash, and tobacco. Currently, 95% of U.S. soybean and 90% of U.S. corn is genetically modified.
Other terms associated with this newly discovered technology are genetic engineering, genetically modified crops, or even genetically modified food. Some examples of gmo in crops are cotton, rice, soya and maize. In farm animals, examples of gmo are salmon, pigs, cattle and chicken, all of which have been genetically modified to improve milk quality or resistance to particular diseases. As good as improvements in the gmos seem to be, however, there are disadvantages to introducing gmos into the daily diet of humans.
