Is this a charcoal?

Hey folks! I have this adult corn snake here (unsexed, tail shows sign of male), either way, I'm unsure of its "base" genotype (visual morph). It's origins are unknown, for it's a rescue. It was advertised by some very poor snake caregivers (no water, poop everywhere, dry cedar chips and pieces of shed everywhere) as a grey ratsnake. Very little yellow along the chin, almost a keeled scale look. I breed white oak's and this is some type of anerytheristic corn snake. Suspect charcoal, obviously unproven. I plan to breed, so that's why it's "important". If YOU had to say, what morph is this? THANKS FOLKS!!

It can be difficult to determine whether a corn snake of unknown lineage is anery type A or B (charcoal). I have seen type A animals with little yellow and charcoal with a considerable amount. The only way to be sure is to test breed it to an animal of known lineage.

Thank you for your response! I suppose I'll be in the market for a charcoal female! If they pop out normal, than this is an anery A (which honestly, I would be very surprised).
