Genetics are a strange thing. You have regressive genes and you have dominant genes. Were your seeds F1, F2, F3, F4? What do you know about your seeds, how were they made? Sue has several breeders as friends and I bet they can give you a more comprehensive answer than me, but basically - sometimes the auto gene can show up if rureralis has been used to create the strain or one of it's parents or parents parents. Depending on how stabile the strain is, these things happen now and then. It's a shit thing, but you can't guarantee yourself 100% against this happening - Unless you shy away from unstabile strains that has the ruderalis gene.
That would also include the Devil's carnival strain Sue's a part of creating now. There you have both auto and photo-seeds showing up. It's actually much more interesting than annoying if you ask me - But that's just because I want to learn breeding. So am trying to understand these things - please correct me folks if I am giving away misinformation, but this is pretty much how I understood that thing.
