Statistical Parsimony network of Lacerta lepida β-Fibrinogen intron 7 alleles from 104 samples. Open circles with no numbers represent unsampled or extinct alleles, and the filled black circle represents the outgroup (Lacerta pater). Pie chart shading represents the proportion of each allele found within each mitochondrial phylogroup. Colours in pie charts are the same as those used to represent mitochondrial phylogroups in Figure 3. Dashed lines represent ambiguities in the network.
