Is this snake a blackback?

[Jerhart]

According to this from Ralph's page - the only TRUE genetic black backs are het red axanthics.

Anything else is simply a descriptor. There is far more "black back" on the pictured snake than dorsal patterning. I would describe it as a black back myself, and apparently, Ralph also described it as such on the care card that came with the snake when originally sold to Randy.

So, who's wrong? Ralph when he described it as such when he sold it?

.....perhaps the name "Black Back" is incorrect then? Just like how Patternless Leopard Geckos were/are called lucys even tho they are not try leusitics? I duno...."black back" just doesnt seem like the right name for the phase then. If someone tried to sell me a snake like that above at an inflated price because it is a "black back," I wouldn't bite...again, it looks like someone trying to get an extra buck from a normal....we have all seen it before....

At best, that snake is a dinker.
