Normals can be het for genes with no external discernable markers for the gene itself.

How do you know its a het?

Get it from a reliable breeder.

Pied hets can have a marker, which are side belly markers (two dark lines towards the base of the tail).

Without knowing the hets, you could get any recessive morph at all, IF, and I stress IF the animals are BOTH hets for the gene.

You cannot get an Albino Pied from having a Het for Albino and a Het for Pied.
