Why are there different color phases of albinos?
The variation is the same mechanism that you see when you compare a normal wild imported leopard gecko to an orange phase designer gecko. If you take a wild imported leopard gecko and strip away all black pigment then you would have a “normal” wild-type albino. By introducing all my very best designer genes into our albino line each year we have been able to make “designer albinos” improve each season. You can make a more attractive leopard gecko from a wild-type pattern whether is is an amelanistic albino or not.
