I don't think we are on the same page. I am NOT saying I could fix th trait in three generations. NO way no how. What I was alluding to is the fact that all the big players in the asian breeder market on now working on these heckel crosses. Tony Tan, Wayne Ng, Jefferey Yang, Wantanabe, Forrest, just to name a few. From this HUGE collective of tanks and breeding knowledge, I feel that fixing the trait (by them) is obtainable. I think THEY can reach that goal in the next several years.Strain definition was on the agenda I wanted to get a time frame worked out first.....you say you need 3 generations, sounds good and i agree to that.
I then went on to say or define what I considered at what point that achievement will have been met, which was producing a heckel cross that could pass on the trait in at least 50% of the offspring for at least three generations (at which point I think they would most likely need to be bred back to a heckle).
I think the heckel bar acts simular to the blue halo genetically, albeit a bit more rare, but eventually could be fixed to a certain extent.
