Figure 1.

The ncpGS gene tree and the AFLP tree. A. Unrooted Neighbour Joining phylogram of 10 diploid Achillea species (seven of and three outside A. millefolium agg.) based on the ncpGS gene sequence data. The tree contains 31 ncpGS haplotypes generated from 186 clones (sequences) from 49 individuals of 20 populations. Bootstrap supports (> 50%) from both methods (NJ/MP) are shown next to the major branches. Labels of terminal branches are written as "taxon abbreviation (population code-number of individuals/number of clones)". For taxa abbreviations, see Table 1. B. The AFLP tree from a previous study (Guo et al., 2005 [10]) for comparison.
