Figure 3 . Multidimensional scaling plot (MDS) showing first two coordinate axes for all global samples of Plantago major (385 samples from 50 populations worldwide), generated by creating a distance matrix using 2807 of the most informative SNPs in ngsdist. Colour coding reflects ancestral populations (at K =6) modelled in ngsadmix (see Figure 3).
