highly significantP < 0.005
The Mantel test showed a highly significant positive correlation between the pairwise genetic differentiation ( F ST ) and the geographic distance for the whole dataset ( r = 0.706; P < 0.005) and for the Moroccan populations ( r = 0.698; P < 0.005), but not for the Iberian populations ( r = 0.002; P < 0.005).
