Which leads to the question: GMO corn is unable to reproduce. Are GMO people?
Good question. BTW, potatoes, many which are hybrids, will revert back to the prior seed if replanted. They dont hold the genetics. If you take seed from the corn that you grow and replant it, I understand it will eventually revert back.
Commercial maize is another matter altogether.
BTW, there is no such thing as anything other than hybrid corn/maize.
