Its not the breeders job to inform you what they used to make up their snakes. If you don't know what the morph was created with do the research yourself. I am not a breeder and I can not name half the morphs in the ball python world but I do still enjoy seeing what has been created. I do not require a description for every pic I see. You should just be happy the breeders take the time to share the pics at all instead of complaining about it.
Maybe you would enjoy the Genetic Wizard on World of Ball Pythons site.
