Fig. 1 Summary of ds, dn, and ds/dn values for all sequences analyzed. "epi avg" is the average with respect to pairwise comparisons between Epifagus and other sequences.




Fig. 2 ds/dn versus nucleotide position (bp) for ycf2 sequences. The "100", "150", and "200" lines represent ds/dn calculated over intervals of 100, 150, and 200 bp, respectively.
