>It would stand to believe all boa albinos seem to be T positive because they have the ability to produce red and yellow coloration.

In mammals this would be correct. But fish, herps, and many birds have red and yellow pigments that are not melanin. They are pyridine compounds, if I remember correctly. Corn snakes have been tested and fround to be tyrosinase negative. They lack the black coloration caused by melanin but still have their red, non-melanin pigment.
