Hi Andy, That is an Actual T positive. What I'll do is take a picture of the T positives next to a normal. That will help show the difference. Also, the Hets of a T positive look just like a normal. Tracy Barker has some nice looking hets. Maybe she'll post some up. The T stands for Tyrosinase which is an amino acid which is Amelanistic. The gene disalows a certain pigment to enter the chromosome. Therefore you have a different genetic look to the Boa in a different form of Albinism. In a T Negative Albino Such as the Kahl or Sharp strain Albino, you have Tyrosinase (the amino acid) which is completely absent. In a T negative such as this Boa I pictured, tyrosinase is present but it isn't able to function in the same way it does in the other form. (Such as the Kahl strain). Different Colors Show up. However, the Tyrosinase blocks certain Pigments. Therefore the Color difference.
I know it is kindof confusing. The T positive Columbian Boa looks like Black is allowed, but it really isn't black. If you look close, it is a lavender color. The CA T positive is different. At least the Nicaraguan version that I have. I know there is another T positive CA Boa. I think there are 2 more actually from a different Local, but I don't have that much info on them to comment. The Argentine Boa is also has T positive version. It is similar to the Nic Boa. I love all the versions, and I think All are unique in their own way. Different people have different tastes, and likes, but I just LOVE THE COLUMBIAN version, and I love the CA verion too. I love the Argentine version. They are all awesome!!!!
I'm sure there are a few other snakes out there that have different Amino Acids that are blocked, therefore a different Genetic apperance. However, they just have to be proven. They may even look more or less drmatic then the VPI line that has been proven. The Future is so much fun to think about. It is Amazing what Genetics can do for the looks of the Boa Constrictor.
Take Care, Jeremy
