<b>A.</b> The numbers above each branch are the Bayesian posterior probabilities (again after burn-in trees discarded), and those below the branch are the support generated from a likelihood bootstrap analysis (n = 1000).</p>
<p>The HEG tree is unrooted (it is unknown) and displayed in such a way as to minimise the differences with the host tree.</p>
<p>
<b>B.</b> The null distribution for the likelihood ratio test generated by evaluating δ for 1000 non-parametric bootstrap resampled data sets, 50% of which are drawn entirely from the host data and 50% from the HEG data.</p>
<p>The likelihood ratio for the observed partition is shown.</p></div
