Welcome!
I will leave the answers to some of our Board members who have experience with hybridizing. I'll just say that it's complicated... and not altogether predictable. Even the most experienced breeders get surprised... they make their best "educated guess" (so that they don't waste years and lots of bench space) and then hope that they get what they were looking for. And in a seed cross, individual plants will be different so then they pick the ones they're interested in further propagating, or cloning, after the seedlings bloom. There's certainly plenty of science involved, but also a roll of the dice when all the factors get combined.
