Too simplistic.
T- albinos are albino because of a nonfunctional tyrosinase enzyme. T+ albinos are albino because something else in the genes and biochemistry isn't working. And that something else could be different things in different T+ albinos.
In species like the lab mouse and (we think) the corn snake, there is at least one mutant gene that produces partly functional tyrosinase. There is melanin, but the animals are lighter than normal.
A couple of years ago I asked Dave Barker whether Sharp or Kahl strain was T-. He didn't know because nobody has tested either strain. Unless there has been a test since, we still do not know. And possibly both strains are T+.
