Figure 1.

Maximum likelihood (ML) trees of gobionine species belonging to the genera Pseudorasbora, Pseudopungtungia, and Pungtungia inferred from multiple nuclear genes, that is, the recombination activating gene 1 (rag1), recombination activating gene 2 (rag2), and early growth response 1 gene (egr1). ML and Bayesian inference (BI) trees were reconstructed after partitioning the concatenated nucleotide matrix according to genes. Bootstrap values above 50% of ML analysis and posterior probabilities above 0.90 of BI analysis were shown at each branch node. The scale bar indicates substitutions/site.
