Figure 1.
PCA derived from Y-chromosomal haplogroup frequencies.
The two leading principal components display the variance. The superimposed biplot shows the contribution of each haplogroup as grey component loading vectors.

Population genetic structure vs geography.
Genetic barriers (A) and MDS plot (B) based on the ΦST's distances between populations derived from Y-STR data.
Figure 3.
Composite BATWING population splitting.
The composite tree is constructed from data sets described in the text, based on the results displayed in Table S6, with a pruned leading topology and averaged times. Numbers indicate branch lengths measured in thousand years.
