Scatterplot from a discriminant analysis of principal components (DAPC) (a) using the four a priori groups. The sample origins are labeled within their 95% inertia ellipses, and individuals are connected to the corresponding group centroids. The number of PCs retained and discriminant functions are shown. Bar plot from DAPC highlights the membership of individuals in different groups according to geographical zones for both wild and cultivated olives (b).
