Saami dimension in the PCA

Saami and Finns have always been close to each other in the higher dimensions of the PCA plots and heatmaps from the previous analysis, however in dimension  D1-D6 the Saamis clearly diverge away from the others in the panel into their own dimension. Finns here appears here to go in a complete opposite direction sharing space with Vologda Russians.

We see very clearly in this dimension the individuals of main Saami ancestry cluster into their own dimension while Finnish and Scandinavian individuals with Saami minority ancestry pull straight towards the individuals of mainly Saami ancestry.

This likely means that Saami do have distinctive haplotype segments that seperate them clearly from the other populations including Finns.
