Figure 2.

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