Jumping back to this, you're referring to a chimera, where one animal contain, more or less, the mashed together DNA of two animals. So, this begs the question, are chimerism and paradoxing the same thing? If so, then this wouldn't necessarily be something you can breed for.
However, I'm almost convinced they're
not the same. Take a look at these two snakes, both owned by Taylor Nicole Dean:
This is Gemini, who is a chimera.
From what I've seen, this is how chimeras tend to appear, with a visible distinction between the 2 sets of genetics.
On the other hand, this is Frank:
Frank is more what is expected of a paradox, with splotching and banding of pigment visible.
I have also noticed and agree that paradoxing seems much more common on morphs that minimize pigmentation, so it appears that these are patches where the pigment actually expresses. Given these, it appears that chimera and paradox are two different expressions. They visually express very differently.
Still, I'm not sure that either of these can be bred for consistently.
