Merle Ratling

[Michelle.C]

Neither parent looks like him. I don't know who his mom is, there are 4 girls in the tub. What's the difference between merle and chimera?

Chimera is non-genetic. It's when fraternal twins merge and develop into one individual. Similar as Paradox in Ball Pythons and other reptiles. Since Merle is dominant and neither parent was Merle, I'd imagine this guy is a Chimera/Paradox. You can always breed him back to his dam/siblings and see if it's genetic though. It's possible that one parents was just a very poor Merle. Either way, this guy is wicked awesome and I'm jealous.
