Driving through Iowa in the 50s I remember seeing signs on the cornfields touting this or that hybrid. I understood that the corn they grew had to be planted with factory seed because the hybrid wouldn't reproduce itself. Maybe cloning isn't quite as outrageous as genetic engineering. There are people who want the genetic engineering here and now for themselves and their children. I think it is a Bad Idea. A lot of people want only perfect babies, and soon they will want only the new, improved, hybrid perfect babies--factory seed.
In the 50's that was probably hybrids created using cross-polination. And I think that's only true of some hybrids.
Some of the Frankenfood like the genetically engineered corn, does self-reproduce, because farmers have complained that the genetic traits are jumping into adjacent fields.
So I think we have already crossed that bridge.
