The probability is very low and should therefore be practically equated to zero. 2. The antibiotics used in the selection are in little medical or veterinary use at the moment. 3. The next generation of GM crops will use different technology. These statements of the usual answers are intended on the one hand to be accurate & fair but on the other hand also to hint at the reasons why some scientists like me are not satisfied with them.
