Overall, the sequence divergence is smallest in SSU, followed by psbA (Figure 14).
On the other hand, if the BuT2 divergence is smaller than the nuclear gene divergence, HT can be suggested.
Within clade sequence divergence was small, with 0-3 base pair differences between the different strains of F. fomentarius from Northern European countries.
From Figure 5, we see that the values of the KL divergence were small for all observations.
When CDL was measured at constant temperature, the evolutionary divergence was small but significant, but when a thermoperiod was superimposed on the photoperiod regime, the differences between populations were larger and the divergence from the original CDL values became greater.
The average correlation between branch-specific protein divergence and expression divergence was small, but this is not surprising, because many genes will presumably experience similar selective pressures in all lineages.
The observed divergence was smaller than reported in other fishes (e.g. zebrafish: [ 25]; rainbow trout: [ 111]; medaka: [ 109]).
The position of ND1 along the third axis suggested a certain level of admixture with shorthorn populations, most probably of BAO origin, according to their sampling area, although pairwise F ST divergence was smaller when compared to SOM (Table S1 in additional file 2).
When the variance of random divergence times is small, all of the models in Table 2 are expected to struggle to detect this variation and will often incorrectly estimate highly clustered models of divergence (i.e., few divergence events).
