Great looking animals! I especially like to two abberant ones.
It's amazing how many different lines of this mutation (or very similar mutations) there are out there now!

But one question..It was my understanding that no one had actually tested any reptiles to prove the presence or abscence of tyrosinase? According to the Barker work it's a simple test (involving dopa I think) but even with the results of this it would still not be conclusive regarding "T positive" being an accurate description for snakes showing this and similar mutations

I think that some of these T positive Colombians look like "classic" hypomelanistic animals to me. At least they look more like what's been called hypomelanistic in the past than they do the mutation that Caramel Ball Pythons, the Argentine Boas or the T positive Blood Pythons are exhibiting. I can see how with all the forms of dominant/incomplete dominant hypomelanism found in boas already it would be confusing to call them Hypomelanistic, but I think that's more descriptive of what they are...hypomelanism expresses itself in many reptile species as a recessive trait why not Boas? This is just my opinion, and it isn't meant as a slight toward ANY of these animals as I find them all to be quite beautiful and of course very desirable. And I reserve the right to 100% WRONG . Just a thought I wanted to throw out there to see if anyone else had any input?
