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

Has anybody given any thought to this being the source of Extremes? Many of the recent posts about Extremes have centered around Snows that look gray, Anerys that look brown and possible Hybinos that look lavender. Take a look at the T-Positive Nicaraguan Boas. The Hypo Nics have a cleaner pattern but the black areas are still black. The T-Positive Nics are much cleaner and the black is reduced to a gray color. Does this not sound like an Extreme Hypo Honduran. This may also explain the theory that the Extreme gene is seperate and apart from the Hypo gene. Could this be the reason that a Snow or Albino has color added to it? It does not appear to be a logical argument that a Hypo gene would add color to a Snow or an Albino. What do the rest of you think?

Thanks!
