Daniel, I checked out that link....I see what you are saying. From the looks of my snake, compared with Nerd's and Joe Campell's pics, he could be a black back. However, just like you said, It would have to be proven genetically. That is why the loss of Cyrax (the father) was sooo devastating.....Given that the baby (Gambit) has a similar looking brother from the same clutch, I am hoping to breed him back to his mother when he is old enough, so that I may find out once and for all.....darn all this waiting!!!!
