Figure 5. A, median-joining haplotype networks of mtDNA cytochrome c oxidase subunit I sequences for Ophryotrocha mediterranea. Empty circles represent missing haplotypes. Black points represent mutational steps. Circle size and pie size are proportional to the haplotype frequency. B, haplotype distribution in the studied populations of both lineages 1 and 2.
