A: Farmers have grown commercial GM crops for over 20 years, but genetic modification in crops is much older. Farmers have been intentionally changing the genetic makeup of all domesticated crops for about 10,000 years. Every fruit, vegetable and grain that is commercially available today has been altered by human hands, including organic and heirloom seeds.
Then, in the late 20th century, advances in technology enabled us to expand the genetic diversity of crops through genetic engineering; a major result of this was GM seeds. Kent Bradford, director of the University [...]
A: The 10 genetically modified crops available today include: alfalfa, apples, canola, corn (field and sweet), cotton, papaya, potatoes, soybeans, squash and sugar beets.
Below is a table outlining what year the ten crops became commercially available:
Hi! I would just like to verify that the crops listed are the only crops currently genetically modified in the US as of April 2019. Thank you!
A: GM crops on the market today have the same nutrition and composition as non-GM crops. Therefore, GMOs have no effect on the human body. Connie Diekman, Med, RD, D, FADA, explains in a response to a similar question. Read the full response.
“The Food and Drug Administration has set forth guidelines related to the use of GMOs, and in those documents they reference the science that indicates food developed through biotechnology are digested in the same manner as other foods and therefore provide the same nutrition.”
We hope this answers your question, if you have any other qu [...]
A: A hybrid is a plant that is the result of crossing two species or varieties. Hybridization can happen naturally, but is most often an intentional way to select traits from two plants with the goal of maximizing those in the offspring plant. This process can be part of traditional plant breeding methods, but some hybrids are also GM crops if either one or both parents used in a cross are transgenic plants.
For example, corn is one of the most widely hybridized crops in the world, and farmers have been using hybrid corn varieties for about a century. Using biotechnology, breeders can also ad [...]
