Fig. 2From: Parapatric genetic divergence among deep evolutionary lineages in the Mediterranean green crab, Carcinus aestuarii (Brachyura, Portunoidea, Carcinidae), accounts for a sharp phylogeographic break in the Eastern MediterraneanTCS haplotype network of Carcinus aestuarii, based on the alignment of 587Â bp of the mitochondrial gene Cox1, showing the relationships among the recorded haplotypes. Haplotype 2 corresponds to the ancestral haplotype. Small black circles correspond to missing (or hypothetical) haplotypes. Each line between two points represents one mutational step. Circle sizes depict proportions of haplotypes; the smallest corresponds to 1 and the largest to 67 individualsBack to article page
