actually he will get 100% pieds with a pied x pied.
to make albino pieds you need at the very minium an double het pied/albino bred to another double het pied/albino. breeding them yeilds these results...
getting snakes genetically farther will increase your odds, to use your male pied, you would breed him to an albino, the babies would all be double het pied/albino. breed them together would give you the above results.
