Fig. 8
Most parsimonious Median-Joining Network (ε = 0) depicting the phylogenetic relationships among, and geographical assignment, of C. oxystoma COI haplotypes. The size of each circle is proportional to the corresponding haplotype frequency. Branch lengths are proportional to the number of nucleotide changes between haplotypes. Black circles indicate median vectors (mv) that represent hypothetical missing or unsampled ancestral haplotypes. Number of nucleotide changes indicated on longer branches
