Gregg, how did you come to the conclusion as to what is a T-pos and what is a T-neg? Do you have any scientific proof to back this up or are you basing this just on phenotypes and what is commonly accepted by the general consensus?

I'm not trying to be difficult about this or an ass but it got me to thinking about just how much we really know what we are talking about when we try to be definitive about the whole Tyrosinase definition. Heck, even I subscribe, ignorantly I might add, to thinking that our "normal" albinos are T-pos while the "Hypos" are T-neg. The reality of it is, I have no way to back this up either other than by going along with the general consensus of what is currently accepted. But does that mean that the general consensus is correct or that they even know what they are talking about or have the means to prove or provide even an ounce of proof? I do not entirely believe they/we do.

Like I said, I got to thinking and decided to try and research this a bit more. Along my searching journey so far I came across this interesting thread ( http://www.cornsnakes.com/forums/showthread.php?t=16720 ) which goes quite in depth about Tyrosinase and how it is being defined. I think everybody that "thinks" they know anything about what is T-pos or T-neg should really read this thread because there was a lot of scientific debate going on rather than people just accepting the general consensus of belief and simply restating it.

I believe a whole lot of investigation and proof needs to be delivered before we simply start tagging scientific and genetic names onto phenotypes without really knowing whether it is true or not.
