Please take this the right way: I have eight normal ball pythons, and also have 7 ball pythons that are 100% het for different recessive genetic morphs ( albino, caramel albino, and pied ). To tell you the truth other than my het pied male they all look 100% normal. The only reason my het pied male looks different is because of his ringer which doesn't assure his heterozygous genetics. The only thing that assures me of that is the parents of him.

I'm just trying to be educational when I say, and I've learned from hard lessons the only way you can tell if an animal is het for any trait is know the parents, or breed it to another het or better your chances by breeding it to a homozygous for ( visual morph ).

As for the ball python in the pictures. It looks 100% normal. I woke up 3 of my normal females to compare, and they agree that they could be twins with your snake. BUT... It does in fact have a very nice pattern, and light coloration.

So anyway nice normal possible het. As everybody else though I've gotta ask what is it het for?
