A target branching functionality of around 15 side chains per backbone chain and a constant branch molecular weight of either 5000 g mol−1 (seriesries) or 30 000 g mol−1 (seriesries) were used for each generation.
A tree of height 9 and constant branching factor 100 has (100^9 = 10^{18}) leaves, which is indeed sufficient.
First, we maintain a constant trunk length of l 5 = l 6 = l 7 = l 8 = 10 m, a constant branch length of l 2 = l 4 = 10 m, and a constant link branch length of l 9 = 20 m.
If one of the branches is constant, it is either the neutral element or the absorbing element of the binary operation, which means they can either be collapsed into the non-constant branch (neutral element) or to the constant branch (absorbing element).
A constant branch pattern of the vascular supply of the medial and lateral femoral condyle, related to the height of the transverse osteotomy cuts in distal femoral osteotomies was observed.
Constant branch lengths were assumed.
Both traits were influence by systematic position within the Tropidurinae lineage (significant phylogenetic signal, see Table 2) under most models tested (clutch size exhibited marginally non-significant phylogenetic signal under constant branch lengths, P = 0.051, Table 2).
The first was a tree that included constant branch lengths, whereas the second tree alternately varied +/- 50% of a given branch length.
However, the branches of the trees for each underlying data set (sequence, sequence-structure and doubled sequence) received higher bootstrap support values and fewer false splits with constant branch lengths compared to variable distances, though differences were minimal (Figs. 1, 2, 3 and 4).
Another oversight that could lead to non-constant branch lengths along the alignment is the fact that both data sets consist of multiple genes.
