Therefore, the coevolving plants and insects should have star-like phylogenies trees that have short internal branch lengths typical of rapid speciation events.
Twenty vascularization cases were studied for the external branch of the sphenopalatine artery, and 10 cases were studied for the internal branch.
Waterfront, it turns out, is an internal branch of GMMB.
Internal branch topology was validated via the interior branch test.
Internal Branch Tests were conducted using 1000 replicates.
The shorter this internal branch, the fewer expected genetic changes and the less NST signal, so in general outgroups that minimize NST internal branch length are preferable.
As Fig. 6a shows, integrating over internal branch lengths causes LBA.
Reliability for internal branch was assessed using the aLRT test [50].
Using a pre-duplication outgroup (Figure 1b), the length of the NST internal branch is d.
At the true internal branch length of zero, the three possible trees have equal likelihood, but incorporating longer internal branch lengths causes the integrated likelihood of the LBA tree to dramatically exceed those of the other topologies.
NST signal is due to changes occurring along the aberrant internal branch (red in Figures 1, 2, 3).
