The percentage of polymorphism (P), the Shannon diversity index (I), the Nei's genetic diversity (h), the Nei’s genetic distance (D), the coefficient of genetic differentiation (Gst), and gene flow (Nm) among the populations were calculated using the POPGENE software version 1.32 . A dendrogram was constructed based on the Nei’s genetic distance with UPGMA (unweighted pair group method using arithmetic averages).
