First, I never said you didn't know how to bread snakes to get the results that you wanted. I am quite sure that you can and do.
What I have said is that by definition a snake with pink eyes is not leucistic. Yes, you can have a white snake with pink eyes, but since it has that eye color, it is not leucistic. That term should not be used. Such words have specific meanings and you are using term incorrectly. I have also said that your cross examples were overly simplistic, and were done by phenotype and not by genotype. All of this is still true, but if you read the article, you would also see that you were somewhat correct.
If you read my last post, It is clear that we have both been wrong in parts of what we were saying. If you read it, then you now know that there are two traits that can cause a black rat to be albino. There is also a separate and independent trait that causes a snake to be leucistic. If a snake is homo for the same albino trait (we are talking about for the black/brown coloring only), and is also homo for the leucistic trait, the snake will have pink eyes. If it has pink eyes, again, it is not a true leucistic snake. What I would say if I had such a snake, is that I had a white albino snake that is homozygous for the leucistic trait.
I am not trying to put you down. I have never called you names. The article I posted was a summery of someone else’s work into this very complex subject that we have been posting on. It was on topic. I think the article is worth the time it takes to read and digest. It sheds light on some of what is going on with crosses for color, and why the results come out as they do. On the other hand, it in no way explains everything. Something’s are known from experience before they are understood by science.
Peace
