d.f., degrees of freedom; grouping of populations: Chinese group (populations C1–C7), Japanese group (populations J1–J7; for population codes see Additional file 1: Table S1, Supporting information); ** P < 0.001.
Estimators for Tpi and ITS were calculated based on the infinite alleles model (F-statistics) and those for nSSRs on the stepwise mutation model (R-statistics).
