I did not think that it was possible...but I'm so far from being an expert on the genetic side of things that I wouldn't be the one to ask either. Auto's have actually become extremely stable in the past 10 years...the idea of "auto's are unstable, unreliable, unpotent and not heavy yielding" is a mindset that is simply out of date in modern growing. Auto's have become quite stable, WHEN purchased from reliable breeders. FastBuds and Bomb Seeds have had a damn near 100% success rate in the 75 some plants I've grown from seed, from them.
