GSF or more likely high % GSF. One thing is clear no matter the genetics. The fish are reproducing at a high rate. That must be dealt with.
"wouldn't it be possible to have HBG Fx offspring that have mostly GSF traits" Only if the back cross or out cross was a very high % GSF.
Childers -- " ...F1 hybrids, seven were predominately males (RB, BR, and BG were 97 percent males; WG were 84 percent males; and RG, GB, and BW were approximately 70 percent males), two were approximately 50 percent males (GR and RW), and one was predominately female (GW was 16 percent males). Ricker (1948) determined the sex of 428 BR F1 hybrids in Indiana and found them to be 97.7 percent males."
We really don't know much about FX +s. At what point do certain traits disappear or significantly reduce. For example skewed sex ratios. If a given fish is an FX that is 1/32 BG and 31/32 GSF has the sex ration trait moved from 97% male to 55% male. Don't know. With some species the FX can be sterile.
