Hybrids which can breed cannot produce pure specimens of either species they derive from. Subsequent generations from hybrids (which are termed "Fx", as opposed to the original "F1" hybrids) carry a plethora of mixtures of the two parent species' genes (as opposed to the 50/50 mix of the original F1 hybrids). BGxGSF out generations have individuals that vary from "almost" BG to "almost" GSF, but the odds are astronomical against getting actual BG or GSF.

If you manage your pond to allow GSF traits to predominate, your Fx generations may likely resemble GSF more than BG; conversely, if you manage to encourage BG, including having sufficient bass predation to eliminate the smaller GSF-type bodies, Fx fish will likely tend to be more BG-ish.

But you're not going to get Green Sunfish.
