  1. Entries are given for the entire Iberian Peninsula (IP) and the four genetic clusters detected using all populations available (N = 278). The two models include IBD, IBE and IBR, and IBE given the principal analysis components (PCs). Akaike information criterion (AIC), ∆AIC and model weight are reported
