Back to the GSF. When the GSF and BG come together, like in many of the ponds represented in this thread. Jim in your experience and observiation, do the GSF or BG traits dominate? I'm guessing you see hybrid vigor through the first gen. I have read that the GSF traits dominate and over time the HBG look more like GSF than a BG. Can the cross go both ways...male GSF X female BG or male BG x female GSF? If not why? Also I have read that the majority of HBG are male...what causes this? They are not sterile like a mule or do you see that??

Sorry if I'm asking to many questions but when they pop in my head they don't leave until I ask...yeah I was that kid in school. lol
