Not a geneticists, but I am a research biologist by career.
And it's not that I'm closed minded, its that some of your theories make no sense and contradict each other. Research and develop those thoughts more on these animals, then present your theories again. You're going into this blindly.
Research more on reptile breeding or genetics in general. From your example, a green snake parent can have yellow or blue offspring. Those offspring cannot carry the green gene.
Here is it in BP terms: a pastel + lesser = pastel lesser. The pastel lesser can have pastel and lesser offspring when bred to a blank slate normal. Those offspring do not carry 'pastel lesser' so they cannot have pastel lesser hatchlings with a normal. And the pastel offspring does not carry any lesser genes. And vice versa. Otherwise it would be a pastel lesser.
Here is some insight. Most lines of morph are not stemmed from the same animal. All the pastel lines did not branch from one pastel here in the states. They are from separate imported animals with the same mutation of different variation.
What do you mean " we've lost sight of what makes them a butter or a lesser. "? Do you know what the difference is? Its the name.
What gives you the right to deem what is true and what is not? Perhaps Ralph Davis and the Bells deemed the lesser and butter to look similar since they are the same mutation? How do you know that the original Lesser and Butter looked the same or different? How can you have a designated look for them?
I agree with everything Rosey said.
Yes selective breeding of traits can happen, but that doesn't mean they are different. And what happens when you breed that lesser or butter to another morph that ruins the 'true' appearance? A 'true' lesser to a cinnamon could have 'true' butter looking offspring.
Does that mean you can only breed one 'true' lesser to another 'true' lesser to get 'purebreds'?
(The term pure bred would be wrong since captive ball pythons are no different than wild balls other than their paint job).
Again, do some research and develop your theories even more. As of now, they make no sense. But I can see where you are going somewhat.........
