Ethnically speaking do Austrians resemble more Slovaks or the eastern French?

[Mortimer]

Here it is explained who the Austrians are ethnically it is a good summary, and considers many aspects, genetics, anthropology, culture, history

They also outline anthropological types of austrians, how they look, they say 9% (i think) are balkan-caucasus types. They consider only "native austrians" not immigrants though. So they give a break down of anthropological types of "native austrians".

Native Alsatians are Germans who have been Frenchified. It's a sad story.

I knew the story as there are both German Alsatians and French Alsatians, but could be true that all are German by roots or at least majority of the population
