Not to be a thorn or anything...but if you are out to line breed and prove one way or another, shouldn't you have got a lesser from RDR directly an offspring of platty daddy? I mean...that's like science 101. Get reliable, definate subjects...if you're asking about the possibility of your snake then you are not proving anything, just guessing with what you've got. That is not good science.
Unless I'm missing something?
Also, its generally frowned upon to go tossing around negative rep because you don't agree with someone. Neg rep is for rude, or harmful replies. Not a cry button when someone states their opinion on your question.
