I know that there are several pairings that will produce a BEL. My question is, is there a certain combination that produces a cleaner looking (pure white no markings at all) BEL? Or do all combos produce pretty much the same snake? I’m looking at getting one, and I don’t think I’ve ever seen an adult and I know that ball pythons can change coloration with age and I’d like to get one that stayed as white as can be throughout its life.
