Figure 2.

Average frequencies of cDNA-AFLP fragments in Dactylorhiza allotetraploids and their diploid parental species. White bars indicate shared fragments between the two parentals; light grey bars, markers characteristic of D. fuchsii; dark grey, markers characteristic of D. incarnata; the black bar shows the unique markers for allopolyploids. The error bars represent standard deviation for mean (see also Table 2).
