So morph or polymorph? And what are the the thoughts about Maria?

I've not heard polymorph used to describe a snake, if it's a morph its a morph isn't it? Regardless as to how many mutations it has.
Speaking of polymorphs takes me back to the Emohawk... John may know where that comes from, the rest of you may need this link emohawk - Google Search

NWs are best known for their polymorphism. Two NWs don't equal one morph of offspring. They can all look completely different. That would be why Mama and Snakey had babies tat ranged from white to orange, to blue and green.

Steve perhaps you could post a picture of the thamnophis picture poster project for the newer members if they think that the northwestern poster is good [which it is] then wait till they set eyes on that

Well. I'm wondering if Maria is like Steve's B/W radix, and if Blade is a red morph?

There are only 3 types of northwesterns that I would consider a "morph". Blade is one of them. He's erythristic. Then there's melanistic ones (all black or dark charcoal grey, with very faint or no stripes/markings at all) and then of course, there's albino.

Albino and melanistic are mutated, recessive genes. Erythristics are not. That morph is a result of polygenic inheritance and is pretty common compared to melanistic or albino.

I guess you could also call stripeless ones a morph, but really, it's just polymorphism and they actually have stripes. It's just that once in a while a northwestern will have it's base color and stripe color exactly the same, so you don't see the stripe.

There's also laterally striped (has side stripes) and single stripe(dorsal stripe only) , but again that's just polymorphism.

To simplify, the only mutations known are albino and melanistic. Anything else is just polymorphism. Maria is perfectly normal.
