Figure 1. A in The Black Sea Flexopecten species-complex (Mollusca: Bivalvia: Pectinidae): Shell morphology and 16S rDNA variation

Figure 1. A Neighbor Joining (NJ) tree depicting phylogenetic relationships among Flexopecten haplotypes (GenBank sequences depicted as purple, green, and light blue circles) and Black Sea samples (red and dark blue circles, this study) derived from the 16S ribosomal DNA gene. Outgroups are depicted as light blue square and black circles. Values at branch nodes indicate bootstrap support. The unit of branch-length measurement = 0.05 nucleotides.
