You're absolutely right Ken, it cuts both ways, we won't know one way or another unless the two are bred to eachother.
Whatever the case and whether or not we even ever find out for sure is a matter of snake morph trivia, it makes no difference to the rest of us in terms of value.
It only matters to those concerned with the bragging rights and the only people who have any reason to argue about that are the people who have actually produced the animals. Someone deserves the credit for having the pure dumb luck to do it first (if we are dealing with a single morph), I'm just fairly indifferent to who that ends up being.
They're still going to be some of the coolest boas I've ever seen and I'm still going to want some.
