You should see on the left side it should have a few Morphs listed ie; albino (recessive), pastel (Co-dom), cinnimon (Co-dom). (or black pastel, depending on which pewter)
Which means you have a few options
Albino being recessive means both parents have to carry the gene.
Pastel het albino x cinni het albino
Albino x pewter het albino
Etc
The genetics wizard on that site is hella fun![]()
