If I take a feminized stable autoflower (100 seeds sprouts 99% all auto no retards) and then mix it with Non-auto/photo ("photo" for now on), I know because of the genetic recessive/dominate genes, those seeds will be Photo's

BUT, a small percentage of those (5%) of the seed offsprings will be Auto. So if I plant 100 seeds of the offsprings, 5% are Auto, I get 5 autos from this batch.

My question is, if I cross those 5% off springs with a stable autoflower male pollen, that is a different autoflower strain, will the next generation be Auto?

Here's the kicker, the first generation Auto and the second cross Auto are different strains. They are both auto, but from different sources. One strain is Blueberry, which was feminized, and the other is Early Girl.

What would happen?
