Genomic scan to identify outlier loci subject to selection by Bayescan approach.

<p>Each point corresponds to an AFLP locus. <i>F_ST</i> is plotted against the log₁₀ of the posterior odds (PO), which provides evidence whether the locus is subject to selection or not. The vertical dashed line shows the decisive threshold value (log₁₀ PO = 2.0) used for identifying outlier loci. (A) The result of <i>Mikania micrantha</i>. Shown as red dots, the 38 outlier loci with the corresponding locus number are candidates for being under positive selection. (B) The result of <i>Mikania cordata</i>. No outlier locus under selection is detected.
