Population structure in European landraces. Population structure within dataset EU-Array was inferred using ADMIXTURE for 35 pre-defined genetic groups, colored according to Fig. 1a. Each bar represents one individual consisting of up to 35 colors according to their ancestry proportions attributable to each of the 35 genetic groups. The red horizontal line indicates an ancestry proportion of 50%. Landraces are ordered according to their position in the neighbor joining tree (Fig S3), with north-eastern and south-western European landraces at the top and bottom, respectively
