It is just a naturally occurring variation in my opinion. I have found both westerns and mexicans that have solid and classic bellies. Some of which were within feet of eachother. I also produce clutches of mixed animals every year. There are usually clutchmates that are polar opposites. Some are solid black, while others are very checkered.

I agree with Troy. Unless the solid belly is tied to other traits like seen with the conda or blonde kennerlyi, it isn't going to be a marker for anything other than what it is... A black belly.
