@ReikoX is this correct mate?

Cheers

mating an autoflower to a photoperiod plant will result in some of the seeds being autoflower and some of the seeds will be photosensitive. assuming the male is the autoflower, preserving the pollen from the father and using it to pollinate the seeds which exhibit the autoflower trait will result in even more seeds which autoflower and a smaller percentage which still exhibit photosensitive traits. Pollinating the females which autoflower from this batch should get you pretty close to all of the resulting seeds exhibiting autoflower traits. If not then one more time using the original pollen on that batch surely would

Okay, one more time…

The autoflowering trait is a recessive trait, the photoperiod trait is dominant. We represent this as P for photoperiod and p for autoflower. When we cross two plants, they will each contribute one geen. In order for a plant to show the autoflowering trait, it must have both recessive genes pp, any other combination, PP, Pp, pP, will be a photoperiod. We can get a rough idea of the contribution using a punnett square. So in your example, when we cross an autoflower (pp) with a photoperiod (PP) the F1 generation will be all photoperiod.

F1 - Autoflower (pp) x Photoperiod (PP)

If you cross two plants from the F1 generation (Pp) then you will have 25% autoflowers (pp). Some people refer to these as “Fast” versions.

F2 - Photoperiod (Pp) x Photoperiod (Pp)

If instead in you crossed a plant from the F1 generation (Pp) with the saved autoflower pollen (pp) then you will have 50% autoflowers. They will also be more similar to the original autoflower, and this would be referred to as a back cross.

F2 - Photoperiod (Pp) x Autoflower (pp)

However you do it, to maintain 100% autoflower (pp), you always have to cross two autoflowers (pp) together.

F3 - Autoflower (pp) x Autoflower (pp)
