I know who started the OB as I bought mine from Ben
It is obvious that there is another gene at play to make the Ultras and Graphites. I just don't think it is recessive. If the YB in a OB x YB that makes a Graphite was in fact a " Het." then why do we not have Ultras and Graphites popping up in YB x YB clutchs? Surely someone one get lucky and line up unknown "Hets." if this were the case.
Another reason that I don't believe it to be a recessive trait is that non ultra Ivories from the OB line have later produced Graphites. So if they were " Hets." shouldn't they have been at least Ultras ?
Either it is still unknown what is going on with this gene or If someone has it figured out they haven't posted what those findings are that I have seen.
I wouldn't go writing OB off as nothing more than a YB. They are compatible and OB's can do anything a YB can do, but YB's can't do all that an OB can do. And we have just scratched the surface with this gene. Again I think we will see big things down the road from the OB, but that's just my opinion![]()
