That is understandable to me . Are you saying that the parent (sire) her father, is also no longer a 66% het for granite and he is 100% ? I understand the daughter being 100% . Is it both of them or just the dam?

We use 66% or 50% when trying to identify what babies may be carrying what genetics in a litter/clutch. It means that's the LIKELIHOOD of them carrying the recessive gene.

How do we get 66%? Glad you asked.

When breeding a 100% het x 100% het (animals that look normal but carry the desired gene) you have this break down of babies:
25% granite
50% het granite
25% normal

Because hets and normals look the same there's no way to officially tell them apart until breeding occurs. So we call them 66% since you have a 2 in 3 chance of them carrying the granite gene.
Once they breed and reproduce babies that carry granite their moniker changes from possible het to "het".

If I can breed one granite checkered to just any checkered and get granites then it's an incomplete dominant gene and they no longer can be "66% het granite".

Does this make sense?

Makes sense to me. So I imagine the same would apply to the hoggie I bought that was labeled as a 66% albino. The albino gene would either be 100% or 0% once proved out by breeding.

Since with recessive both parents need to carry the gene it would mean both have proven! So both would be 100% het. Which is awesome for you!
