the t stands for tyrosinase if i spelled that wrong someone correct me but T- are albinos completely lacking the black pigmentation T+ isnt trully lacking all of the black pigmentation like caramel albino balls and albino balls :) caramels are T+.....albinos are T- I really cant explain it any better just google it lol

It's a bit more complicated than that.
T- albino snakes lack all black pigmentation because they have a nonworking tyrosinase enzyme.
T+ albinos lack some or all of the black pigmentation. Some have fully functional tyrosinase and lack the black pigment because some enzyme other than tyrosinase doesn't work. Some have less than fully functional tyrosinase.
Any animal that has some but less than normal black pigment can be called a T+ albino. Any animal with no black pigment can be either T- or T+. It takes a biochemical test to distinguish them, and that test has not been done on any albino boa or python, as far as I know.
The split between T- and T+ albinos is too simplistic. There are many T+ albino mutations. Even when they are the same species, there is no guarantee that the T+ albino sold at one table has the same mutant gene as the T+ albino being sold at the next table.
If this seems confusing, I agree. IMO, the best thing to do is to give each mutant gene a unique name and not worry about about the biochemical stuff until someone actually works it out.
