I don't know a lot about genetics, and I'm hoping some one here can clarify for me. I've read that "broilers" aka cornish x rocks are f2 (second generation) hybrids. Mustering all of my common sense I can only reason that their parents must have been the f1 (first generation) hybrids, and their grandparents were pure breed. I'm hearing that hybrids dont produce offspring with the same characteristics as the parents. I dunno what the F1 cornishx chickens look like, but i do know what the pure breed grandparents look like, and they are pretty different from the F2 cornishx i have. So does anyone know from experience what the F3 hybrid would be like? As far as i can tell, it doesn't revert to the form of its grandparents but if it doesnt stay true to its parents, then what does it do? are they born defective, or do they exagerate their parents genetic traits? i think i may be too curious for this hobby.
