Correct me if I'm wrong, but wouldn't the Monsanto genetics be functionally useless when mixed with unmodified seed? If half of the seed isn't roundup-ready, you can't reap any benefit from it because if you take advantage of its one party trick -- herbicide resistance -- and spray your crops with Glyphosate, half of your crop will die.
