T-positive and T-negative??????/

Hi everyone,

I'd like to understand a little more on T+ and T-

Tyrosinase-negative - an albino whose cells lack tyrosinase, producing a white and yellow/orange snake with pink eyes. A separate albino mutation from tyrosinase-positive.

Tyrosinase-positive - an albino not able to synthesize melanin, but capable of synthesizing tyrosinase, which results in lavender-brown skin color.

What are a couple good examples of each?

Thanks

They are just different strains of albinism put simply.........Las Vagas(T-) and Bell(T+) albino leos are an example I believe......

Apparently Las Vegas is also T+ from the latest I've read. There are some 'dark' LV albino leopards, but not as many as dark Trempers.

I wasn't going to mention it before because there isn't a T- to make comparison with, but a really stunning version of T+ albino is one of the very few T+ Nicaraguan BCI.
