If you start with a male albino or pied and a female of the opposite, you would breed them together. The resulting offspring will carry both the albino and pied genes, they would appear to be normals. The offspring would be referred to as 100% het albino and 100% het pied. You then grow the offspring and breed them to each other. This will give you a 1 in 16 chance to produce an albino pied. These offspring could consist of normals that are 66% het albino and 66% het pied, albinos that are 66% pied, pieds that are 66% het albino, and albino pieds.
Hope this helps.
