Strange to hear this about the F1 and F2 recessive expressions.
Just recently I finished growing out a handful of Berry Freak plants which did not express. They were direct from shape shifters son and some of his initial works involving the parents of freakshow.
I wanted pinnate so I naturally f2’d 4 of these ladies, I had a Dooligah’ male that I used on the 5th lady.
I assumed I would be able to use these f2’s and find the traits I was looking for… however I recently popped half the seeds I made… and not one showed an obvious pinnate…
However the F1 Dooligah’ outcross tray had several heavy serrated showers.
Both trays are in the photo… I have since selected my heavy serrated Dooligah outcrosses and they are grooving in their own pots. I do have an early picture which displays a shower.
So I was dumb founded and thought maybe I had mislabeled my berry freak male… But I have a feeling the pinnate genes are still just hiding in the bunch. But wild to read what you’ve found. Helps me make some heads and tails with what’s going on here.
