I personally like to have a good 2 generations track record for any of my snakes that have multiple genes, and images of grandparents is definitely a plus. I can't expect that for every snake I get, but I can expect that when I deal with a reputable seller. Nick Mutton will trace your snake from him back to wild origin or German Origin depending on the specific species / morph. It's far more common in the Green Tree Pythons for a pedigree to exist because of the amount of farm raised animals on the market, and the fact that long term captive US bred animals fetch a much steeper price, we're talking $200 for a farm captive bred imported snake, versus starting points around $800 for a US captive bred, and $1200+ for a long term US line with grandparent information!

And as far as pedigrees and linebreeding go, a LOT of our clean morphs out there, like banana in kings, came from successful line breeding projects that came from years of work. Without these efforts, we would not have nearly as clean of morphs as we have available, and unfortunately, without inbreeding, some new recessive mutations may not be able to continue without breeding back your HET offspring.

Cheers,
