Chocolate Gene in Spiders?

I picked up a nice spider ball python female today that is pretty dark and the guy I bought her off of said she may have the chocolate gene in her. But he didn't know the lineage from who he bought her from. I've looked at a few pictures online and not to sure she is a chocolate spider. So I guess what I'm wondering is what makes a chocolate spider a chocolate spider?

I apologize for the dark photos I have horrible lighting in my house. I will hopefully get some better pictures in the daylight tomorrow so hopefully these will do for now.

Looks like a normal spider to me and definitely does not have chocolate in him.

Ok thank you. Was just kinda confirming my suspicions.

Doesn't seem to be a visual match to these Chocolate Spiders, your girl doesn't have the floating dots that they have on their sides, or the brown turning her white sides into cocoa-powder. Nice snake, but probably... healthier! ;)

Healthier?

Looks like a nice solid spider. Very nice pick up, congrats.

Spider :gj:

Looks very similar to a line of snakes that JD Constriction has been working with for a while now and he has spiders, genetic stripes, bees and a few others, but they've got a much darker coloring to them than is typical of, and produces the craziest contrast with axanthics and the cleanest stripes. I know he's been working on proving if it's just a good set of genes he has going, or if there is actually some kind of blackback gene he's had inadvertently in a lot of his snakes, but there's just no good way to distinguish definitively, so as best I know of, to date, it's just a good set of genes, no additional gene or morph.

Count yourself lucky that you got an extra nice spider I say.
