F _IS values in italics indicate significant deviations from Hardy-Weinberg equilibrium at p<0.05 after FDR correction following [44].

*We excluded MS166 from subsequent analyses because alleles of many individuals were adjusted by MICROCHECKER (Ver. 2.2.3; [30]) due to null alleles (over 20%; see Table S1).
