I'd be very interested to hear how you can "selectively breed" genetic elements of a salmon into a strain of wheat, which is parallel to certain of the GM experiments.

Eating monkey brains is known to cause a condition similar to Alzheimer's, but that irrelevance aside, it's perfectly possible for a genetic modification designed for one purpose to enter the larger gene pool. Some - such as immunity to a disease - might be welcome; others - such as inbuilt sterility which forces farmers to buy new seeds every year - not so. How is this "silly"?

The wider organic population can't interbreed.

Really? Were you the result of an immaculate conception?
