There's a huge difference between "axanthic lines" which are mutations on different genes (non-allelic, not compatible) and "yellow belly lines" which, when bred together, still result in ivories (thus same gene: allelic if not identical mutations). Some 'albino lines' (toffee/candy and 'albino') are allelic and some 'albinos' are not in the same gene (lavendar albino).Originally Posted by Tsanford
Having heritable traits that are subtle (brighter color, more intense pattern disruption, etc) segregating along with a documented morph (pastel, mojave, albino) leads to 'line' names (Goldblush mojave, lemon pastel, high contrast albino, banded enchi).
World of Ball Pythons is like a dictionary - it helps the community document the language used to describe the animals and their pattern/color irregularities - the organizers there try to filter the noise from the truly heritable traits, but by no means is that resource capable of fine genetic mapping of polygenic traits. WoBP is amazing and beyond helpful, but don't think of it as proof that EVERY offspring from a 'line' will look the same - there's still huge variation in lots of morphs (calico, I'm lookin' at you!) let alone in the subtle lines.
If you're interested in purchasing a specific animal from a breeder, it's best to ask for pictures of the parents (and if you're buying a proven adult, ask to see the offspring too). Part of the addiction of BP breeding is in the mystery of these subtle differences within morphs. You've gotta catch 'em all.
