Figure 3.

Neighbour network analyses of diploid and tetraploid Central European Arabidopsis arenosa (a, c, e) and A. lyrata (b, d, f) species. (a, b) are based on the low-copy nuclear CHS region; (c, d) are based on the low-copy nuclear scADH region; and (e, f) are based on the plastid region trnL-F. Only specimens identified as deviating from the majority within each taxon in Figure 2 are named. Taxon is given by colour: A. arenosa - black and A. lyrata - grey. Ploidal levels are given as circle - diploid and square - tetraploid.
