Just throwing this out to muddy the waters a little more.....

Earlier in the thread someone quoted Ralph as saying the only true blackback was the Red Axanthic - well if you look at a bunch of pictures of red axanthics and their hets - MOST of them tend to have just as much if not more going on pattern-wise in their dorsal area than the posted snake. Yes some have clean black backs and some are patterned.

Agendas aside - what is the difference?

When it's all said and done - a genetic blackback ain't worth any more than a normal anyway.
