If you have an animal that visually shows the trait (albino) and they are in the pairing, dame or sire, then the offspring of the litter are 100% hets for that trait. If you take the 100% het animals and breed them together you will end up with a litter of scrubs where some will show the trait and the rest of the litter will appear normal. Those normal animals are 66% hets, because some will be and some will not, you don't know which until you breed them and prove them one way or the other. I have a WC albino radix, last year when she was ready I paired her with a very high end red radix. 28 scrubs in the litter, all 100% het for albino. They will be/are the base for my breeding stock, and when paired together the litters will produce albinos, maybe some red albinos, and 66% hets. This will get this WC girls genes out into the hobby and a new bloodline of albino will be available for the hobby to work with. Again for gene related questions look at Jeff Benfer's website or older threads when he has broken this topic down, it really helped me to understand it. Not near as well as I would like yet, but I'm learning, it's a journey!
