Fig. 4

Phylogenetic tree generated by multi-dimensional scaling using 401 TMD bands corresponding to Thalos-CCGG flanking sites from accessions of five populations (see top right index). NCM indicates a negative control. The black lines indicate significant separation, while red lines indicate insignificant separation. The level of epigenetic similarity is indicated on bottom. See Additional file 2: Figure S7 for more details on the statistical analysis
