Fig. 2

PCA analysis (breed codes are as in Fig. 1). a Plots of 546 domestic sheep (≤ 6 animals per breed). We checked that removal of either European or Asian mouflons did not change the pattern of the other individuals. Finn sheep are relative to other Nordic breeds shifted toward the fat-tailed sheep. b Supervised PCA of 1477 animals in which the PC values were calculated based on 507 domestic animals (≤ 6 animals per breed; without EFB, KCH, VBN, AMF, EMF or SMF) and have been averaged per breed. See Additional file 9: Figure S5 for svPC3 vs. svPV1 and see Additional file 8: Figure S4 right panels, for the corresponding plots of individuals. c Left panel: supervised PCA of 1477 animals in which the PC values (svPC1, svPC2), averaged per breed, were calculated based on the indicated fat-tailed, Nordic and Spanish sheeps. Right panel: magnification of the area indicated by the dotted line in the left panel. See Additional file 11: Figure S7 for the corresponding plot of individuals
