Probability densities of four parameters in coalescence simulation as functions of length of internode.

<p>Graphical visualization in which (1–P_{Concord-mtDNA}) denotes the probability density of observing discordant mtDNA phylo tree; (P_binom-nuc) denotes the probability density of observing eight topologically concordant nuclear gene trees out nine studied nuclear loci in total; (P_Coal-mtDNA) denotes the cumulative probability of mtDNA coalescence along the internode and (P_Coal-nuc) denotes the cumulative probability of coalescence of nuclear locus along the internode. Note that there is very small intersection of probability densities allowing for observing eight out of nine topologically concordant nuclear loci while having discordant mtDNA tree (see the text for details).
