The fact that you got a snake off of cl and proved it out to be genetic without knowing what it is is aeesome, congrats. But that doesny change the fact that it looks like a million (sarcastly) other pastels we've seen, with or without the BB. Ftom the pictures you have shown of the one clutch you have prodiced, the "BB" and the "pastel", obviously arent genetic together, and you just got lucky with the odds gods. With that being said, until we see something that doesnt look exactly like a ton of other snakes that we know exactly what they are, alot of peoples minds wont change from the black back pastel idea.

Whether or not were right, congrats on some nice looking babies. I personally wouldnt mind having the 4th one pictured in the first set of hatchling pics.
