Additional tests (KS, KST, Z, Snn, FST) confirmed significant population structure, with KS and Z values high for all comparisons (Clade I/II: KS = 6.79, Z = 3.19; Clade I/III: KS = 6.94, Z = 3.11; Clade II/III: KS = 6.84, Z = 3.12) and all S nn = 1.00, with highly significant P -values ( P = 0.0000), supporting strong genetic differentiation and limited gene flow among the clades ( Table 5 ).
