(6,300 posts)There are only two genetic additions to the main commodity crops produced.
And another poster shared them in a reply to you down post. From the USDA.
They are either engineered to resist the effects of an herbicide, or they produce their own bio insecticide. Or both of the above.
That is it. In fact, at first, yields were depressed. I have no idea now if they have been stabilized.
All the complex traits ( such as yield, drought tolerance, disease resistance that is robust and not quickly overcome) are not single gene matters. They are multi genetic and it is with genetic analysis and developing marker assisted breeding programs that time can be saved by only growing out the plants which posses enough of the genes that we believe are associated with the traits desired. And which individuals or cohorts to use in crosses or back crosses.
Knowledge of genetics and using that knowledge is not genetic engineering.
It is plant breeding.
