Figure 2

Phylogenetic trees of mitochondrial and nuclear markers. Maximum likelihood trees based on 577 bp of the mitochondrial d-loop (left, a), and of several clones (cl.) obtained from 580 bp of an intron of tropomyosine, situated between exons 5 and 6 (right, b). Specimen number (sometimes several with same haplotype and locality) is followed by locality information and population number (as in Figure 1 and Table 1). Individuals highlighted in colour possess a d-loop haplotype group of one species but tropomyosine alleles from the opposite species.
