Southeast allele frequencies were correlated with F _ST to the putative starting site (BX), while northeast allele frequencies were correlated with F _ST to the probable arrival site (BT); northeast and west allele frequencies were correlated with F _ST values to the starting site (BO) and the arrival site (AL), respectively (ns: P > 0.05, *: P < 0.05, **: P < 0.01)
