If the sire was in fact an albiino even than breeding to an albino will give you roughly 50% albino offspring.
Het albino will give 25%.
I would consider going for an albino with another gene or 2 you like with that. Then worst case scenario you produce het albino and het albino + whatever else you chose if you were lied to and in you weren't then you could hit some albino and albino + whatever your first season.
