Just a few notes on this.

Crosses can never genetically revert to the parent - they are what they are.

Local adaptation and plasticity can and often do effect what a fish looks like and what traits are outstanding.

Hybrid sex ratios in Lepomis are highly variable - see Childers work. No one knows yet how all of the genetic combinations line up in the parents much less in the various crosses. I was told by one genetists that in each human it is estimated that there was/is in that person about 4 billion possible genetic possibilities . People and lepomis have the same number of chromosome pairs - 23. Granted some of the genetic principals work differently in fish and humans but there are still a lot of possible outcomes in one fish , many times that in one species and I woul think many more in crosses. No doubt there are some dominant traits that will reappear but that is just a tiny fraction of the genetic story .
