I would classify the fish in my last photo as a RES dominant, BG x RES hybrid, while the BG x RES in the other photos I posted appear BG dominant to me.

What I would like to understand better, is how much of a role, if any, the male parent has on deciding the visual bias on a hybrid. Can a MRES x FBG still display a BG dominant appearance?

Also, these hybrids are naturalized in our ponds....I don't have any idea what gen. they are, or even if they've backcrossed.

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
