Thank you for your reply Paul.

So if I have this correct.

1. The no-melanin type Albinos are up in the air to if they are T-Pos or T-Neg.

2. However, the other bloodlines that show a visible reduction in black pigmentation, if caused by a single gene*, these have been simple recessive so far, those could all be technically classified as Tyrosinase Positive Albinos. This regardless of pink pupils or not correct? Regardless of the amount of apparent black in the rings around the tail blotches correct? This varies greatly even within a single bloodline and may change with age. All this because Albinism is expressed in a wide range of ways correct?

Do I have that correct?

True black is not something that can necessarily be picked up with my eye. Is that a true statement? I am thinking that black production or melanin production my be interrupted on some level but may or may not be discernable with the human eye. Is that correct?

* The reason I say "if caused by a single gene" is many Boas have been produced that exhibit less melanin than some other Boas simply through selective breeding or in the case of particular bloodlines such as Pastel bloodline. These Boas showing less black are the result of polygenic traits which are not inherited in same way as dominant or simple recessive traits.

Let me say that we Boa hacks like myself really appreciate your stopping by and helping us out with the more technical aspects of genetics when these questions pop up. Without the assistance of someone like you we are simply arguing blindly with little knowledge of the facts. Thanks again!
