Figure 6 in A preliminary revision of the Gobius auratus species complex with redescription of Gobius auratus Risso, 1810

Figure 6. (A) Neighbour-joining tree based on a 379 bp segment of the mitochondrial control region of closely related gobiid taxa belonging to the G. auratus species complex. (B) Minimum-spanning tree constructed on the basis of one of the 125 most parsimonious trees (tree length: 45; consistency index excluding uninformative characters: 0.7083; retention index: 0.7879; rescaled consistency index: 0.6653), that was identical to the neighbour-joining tree. Each circle represents one mitochondrial haplotype. Black dots indicate intermediate haplotypes which were not found in the sequenced specimens. Each cross bar represents one mutation step. Abbreviations within circles represent species and colour morphs: Ga1, G. auratus colour morph 1; Ga2, G. auratus colour morph 2; Gf, G. fallax; Gx, G. xanthocephalus; OUT, outgroup G. bucchichi. Numbers of specimens having identical haplotypes are given in parentheses.
