To answer your question, yes sort of.
You may want to look at the locality thread that Evenstar started.
Most BCC folks, and I say most not all, are VERY strict about keeping BCC localities pure.
They frown upon mixing localities and subspecies.
The BCI is another story. There ARE still serious locality folks, but over the years the morph market exploded and the morphs we mostly see are BCI.
I don't know enough about morphs and who's mixing what with what to go further, but from all the info I see hand hear from BCC people they tend to be purists.
