>So, how a T positive boa should look like ?

>First of all, the phenotype should be inheritable and only expressed in it’s homozygote form, recessive genes. So, pastels, salmon, ... are not T positive.

Why recessive genes only? Are you claiming that salmon boas do not have functional tyrosinase? Snakes with either nonfunctional or missing tyrosinase are the only ones that are not tyrosinase positive, as far as I know.

I don't know whether the argument is for calling those blonde albino boas hypos or tyrosinase positive albinos. In my opinion, they could go in both categories nicely. YMMV. But then they'd be lost in the crowd. Think marketing! Think unique! Think rarity value! I'd strip the "albino" off the name and just call them blonde boas as a first step.
