When pairing an albino with a normal on the first breeding you will get all hets. With the second breeding of albino to het, you will get on average 50% albino and 50% hets, and no normals will be produced..

The only way to produce 66% possible hets is with a het to het breeding which will also give the odds of 25% albino in the litter as well. Of the average 75% of this litter that look normal, you will not know which of them are het or normal.
