Hey Dizzle, Here's a quote frome one of Mosca's testers:
"Here is the breakdown for everyone, Mosca has Reeferman's F4 and Wallyduck's F5, The Reef line was selected and inbred for the Pink Candy Grapefruit phenotype, while the Wally Line was selected and inbred for the Pineapple Phenotype, Mosca's "Prize Male" is his Wallyduck F5 Pineapple. The reason his Cindy is considered an F1, is because the lines were so diverged, essentially they were two different things, most people consider an F4 as stable(if selection is done correctly, that's the big difference between a Breeder and a Chucker), He used a Reef's Pink Candy Grapefruit C99 as the F1's mother, he used his Wally's (prize male) F5 as the father, both being their own thing, being used as P1's, it demonstrates F1-like hybrid vigor because of that genetics difference, A 50% PCGF C99 & A 50% Pineapple C99, this is how he created his Mosca C99 F1. The C99 BX-1 is a female F1 he made, recrossed to his Wallyduck's F5 prize male.
F1----(Reefs f4 mom x Wly's f5 dad)
Bx-1----{(Reefs f4 mom x Wly's f5 dad)mom x Wly's F5 dad}
The Pineapple yields better, so the BX-1 and the F1 yield the same, with the BX-1 you have a greater chance at the pineapple pheno, than with the F1. Flower time is same length, and any yield lost in the BX-1 is offset because you're supposed to be looking for the Pineapple if you get the BX-1, and the F1 is to find a pheno of each, and a blended pheno."
I hope this helps~BuilttoEnjoy
