T- vs T+ butter house snake morphology?
 

I'm new to the hobby.

I have a few butter house snakes.

They were presented as T+ and I have no reason to doubt. They came from very reputable breeders (experts in many African species including house snakes).

I understanding the scientific explanation of T- and T+. Tyrosinase, etc.
That said, I still search for a better understanding of the morphology?

I've seen photos of T- butter house snakes. And I've seen photos of T+ house snakes, and I have my house snakes. (My two prettiest house snakes are pale yellow but also bright in color, especially in sunlight. There is a very slight hint of orange to their color. One has darker eyes. The other has lighter eyes that are slightly green-gold in color - not red or pink.)

Does anyone know how to tell or determine T- morphology? Does it have to do with the color of the snake? More strongly orange in color? Or does it have to do more with the color of the eyes that helps one determine the presence or absence of tyrosinase?

Thanks for your time.

T- have red eyes vs T+ have black.

Typically T- are more yellow vs T+ are typically more orange.
