Sentence examples for more divergent outgroups from inspiring English sources

The addition of more divergent outgroups to a given dataset already containing an outgroup is known to decrease the reliability of phylogenetic reconstruction, rather than increasing it.

In most tests where the null was rejected, annual species exhibited faster rates of nucleotide substitution than perennial species (10 annuals versus 2 perennials with less divergent outgroups and 8 annuals versus 5 perennials with more divergent outgroups).

If more divergent outgroups were used, five cases (three annuals and two perennials) rejected rate constancy and 12 of 16 qualitative comparisons (sign test, p = 0.038) exhibited longer branch lengths for annual taxa.

The maximum-likelihood relative rate test rejected the null hypothesis of rate constancy in 12 out of 48 comparisons with less divergent outgroups and in 13 out of 48 comparisons with more divergent outgroups.

If more divergent outgroups were used with combined ITS sequence data, three annuals and two perennials rejected rate constancy and 12 of 16 qualitative comparisons (sign test, p = 0.038) exhibited longer branch lengths for annual taxa.

When the same annual/perennial species pairs where compared using more divergent outgroups, two annuals and one perennial showed significantly faster rates by relative rate tests while 11 of 16 qualitative comparisons (sign test, p = 0.105) exhibited longer branch lengths for annual taxa.

The VHT strategy resembles the case of a biologist who samples additional, more divergent outgroup taxa that root more deeply in the tree.

Here, annuals evolved on average 1.6 times faster rate than perennials when a less divergent outgroup was used, while a slightly lower 1.4-fold average acceleration of annuals was observed with more divergent outgroup taxa.

d p-values of a one-tailed sign test with a null hypothesis of equal frequency are indicated in parentheses The first row of each annual/perennial comparison gives the estimated substitution rate (or branch length) with the less divergent outgroup and the second row gives the estimates for the more divergent outgroup.

The proportion of replicates with significant rate heterogeneity for each of the ITS-like sequences was similar between the more and less divergent outgroups.

The top set of parameters in each row represents the less diverged outgroup and the bottom set in each row the more diverged outgroup.
