An individual can spend several years breeding a 'possible het' from the way you explained, possible het X Normal, and not result in anything. I see what you are trying to say....and I would agree if you are labeling them as definite hets....but when you tag them with 'possible' a buyer may ask you whether they are 50% or 66.66% possible hets, this is where you explain the background of the animals.
If you hatch an albino in a clutch from multiple sires...even if one is codom...there is a POSSIBILITY that those normal carry the amelanistic trait too.
....by dropping the 'possible' as you are saying....you are saying there is NO chance that those could be het...even if you hatch an albino? Am I correct?
