Phylogenetic Relationships among Populations of the Vineyard Snail Cernuella virgata (Da Costa, 1778)

Figure 5

Median joining networks for the 16S rDNA haplotypes and COI haplotypes. Each circle represents a haplotype, and circle size is shown proportional to haplotype frequency. Colors indicate the geographic origin of haplotypes. Median vectors (small red dots) are produced by the network program, representing missing or not sampled haplotypes. Branch lengths are approximately equal to inferred mutational steps. Haplotype codes according to those are represented in Table 2.
