im not to sure about that. hypo can also be part of thier skin.
the latin prefix hypo has to do with "under", "below" or "less than usual".
i think with beardies, the "less than usual" part is the pigmentation. im pretty sure hypo beardies have clear fingernails and are usually light colored. they are not albinos, just lacking pigment.
Qouted of relee77:
Leucisism, Hypomelanism, Pastel, and Translucism are all real mutations.
Leucistic, Snow, and Pastel are all Hypomelanistic traits, meaning they lack the dark or black pigment. Translucent dragons lack white pigment and have solid black eyes. As babies, you can see right through their belly!
Leucistic: White, No Pattern, Clear Nails.
Hypo: Lacks dark pigment, Clear Nails.
Pastel: Looks Hypo, but with Black Nails
