Bipartition reconciliation. (a) In order to determine graphically the number of well-supported groups of individuals, bipartitions can be represented on a two-dimensional figure as lines or curves (each of them dividing the group of samples analyzed into two). Some groups of individuals observable in such graph do not correspond to sl-FFRs but rather to intersections of sl-FFRs obtained from different markers: here, this is the case of individual 05Clip048 and of the large group of samples in the upper right corner of the figure, whose support is equal to zero as these groups are not supported by any single marker. Each bipartition is numbered from 1 to 13 to facilitate comparison with the respective lines of Table 1, and is drawn with its thickness proportional to the number of independent datasets supporting it. (b) Bipartitions below an arbitrary support threshold (here, 50%) may be omitted from such graph for the sake of clarity.
