Nettet2. feb. 2004 · To create these linearized trees, the two-cluster test and branch-length test for rate heterogeneity were applied to these trees to test for deviations from the molecular clock at 1% significance . Faster or more slowly evolving sequences were removed and the procedure was repeated until the data set contained only sequences evolving at a … Nettet16. feb. 2006 · Also, the linearized tree showed that the T2R repertoire has extensively expanded to harbor some 10 genes in the lineage of the common ancestors of amniotes, from 360 MYA to 310 MYA . After this initial expansion, however, the T2R repertoire contracted in the chicken lineage and the number of genes decreased to only three in …

Nettet12. mai 2004 · Because the AP3 and PI lineages are in a clade of the angiosperm B-class genes, two results for the first divergence time of the extant angiosperms (nodes c and d in Fig. 5) were obtained from a linearized tree. Using the linearized tree method with a PC distance gave an age of extant angiosperms of 208 Ma from the AP3 lineage and 170 … Nettet1. apr. 2001 · Fig. 3.—Linearized tree for six VB gene groups. This tree was constructed by using Tajima and Nei (1984) distance. The times of divergence between VB gene groups are marked on the scale below the tree, whereas the nucleotide distances are marked above the tree. The shaded bar represents the standard deviation.
