"Some myths, and questions, persist about Todd Palin's Yup'ik ancestry. A few: For starters, the PC terms (I know, I know, but we Alaskans have a set of our own terms, too) would be Yup'ik or (groan) Yup'ik Eskimo if the person is okay with it. Eskimo is not the most popular term to be used by non-"Eskimo" people in reference to them. Yup'ik is best.
NOT Inuit. NOT Native American. NOT American Indian. Alaska Native is acceptable. (I have a big ol' post about this, and the confusion of it, but just trust me on this. You'll make more Native friends this way.) Some of these terms are not even because of PC, but government distinctions.
As for the "ancestry," the numbers of his blood quantum I've heard range anywhere from 1/4 to 1/16. I've seen a few comments of "why does this matter?" Ah... the long raging politics of blood quantum!
