My experience and $0.02, Schroeder.

I stocked equal numbers of RES, HBG, and BG in my pond, like, 5 years ago. I have not seen hide or hair of a HBG, or anything exhibiting any GSF traits, for over 3 years.

The HBG were simply overwhelmed by BG numbers into a situation where I suspect they are still present, but will only be caught a teeny, tiny fraction of the time. I think this is one of the reasons CW says not to stock HBG with BG - what advantages HBG actually have over BG (like limited population numbers) are voided by BG in the same pond.

As ewest mentioned, HBG CAN backcross with BG; I feel the possibility of this is pretty small and is ignorable for those of us without a compelling reason for maintaining pureblood BG (like Cecil Baird, who has monetary reasons for doing so).

I am sure HBG could be crossed with RES, at least in a lab/hatchery setting, but feel this is even less likely in a pond.
