FYI I'm just a regular guy who loves snakes and thinking outside the norm....I again make no claims to know anything...hence the word educated GUESS
I don't dissagree with any of the points you make about different lines!
PLEASE!!!!!!!!!!!!!! just forget what you know for a sec about morphs and all you were thought.....open mind, clean slate!
you got a yellow snake and blue snake, and you find that by breeding them you can get a snake that is green. So you do this, and get a few green snakes, you would still have some come out blue and some come out yellow. I would think that even the ones that look yellow still cary some blue in them so now no matter what they look like they are forever mixed. So no matter what it mates with, it can/and will pop out babies that have any combo of the "original" mom and dad. Making the bloodline forever mixed. Now for the yellowgreen babies and all shades in the middle can either be call one or the other. Is our president "Black" or "White" or mixed and what does that make his daughters? What if they have kids with Black men, would that make our president grandkids less White?...LOL people even question this. Just a idea, it can grow, not an absolute! Taken lesser that look one way and butters that look another, Good ole "selective breed" can prove out anything.....and isn't that part of the fun? Never knowing what you're gonna see pop out the egg?!!!!
