English: Procrustes-transformed PCA plot of genetic variation of worldwide populations.
(A) Geographic coordinates of 53 populations. (B) Procrustes-transformed PCA plot of genetic variation. The Procrustes analysis is based on the Gall-Peters projected coordinates of geographic locations and PC1-PC2 coordinates of 938 individuals. The figures are plotted according to the Gall-Peters projection. PC1 and PC2 are indicated by dotted lines, crossing over the centroid of all individuals. PC1 and PC2 account for 6.22% and 4.72% of the total variance, respectively. The Procrustes similarity is t0 = 0.705 (P<10-5). The rotation angle of the PCA map is θ= 31.91°. |
