Dendrogram of genetic similarity among 14 hawksbill turtle individuals from four nesting groups in the Persian Gulf: Kharkoo (K1–K3), Nakhiloo (N11–N14), Ommolgorm (O1–O6), and Shidvar (S1–S4). The dendrogram was constructed using ISSR markers and Dice dissimilarity distances. The vertical scale represents genetic distance, with greater height indicating lower genetic similarity between individuals or groups.
