The study selection agreement between the authors was 0.73 using quadratic kappa weighting.
The screening of abstracts had a selection agreement defined by a κ score of 0.94 and the screening of full text had a selection agreement defined by a κ score of 0.47.
We assessed reviewer abstract selection agreement by pilot-testing these inclusion criteria on a sample of 100 abstracts.
Comparison of these estimates among contigs identified major functional classes of genes under purifying and diversifying selection in agreement with previous researches.
Thus, our data on parallel evolution of proteins suggest that a majority of amino acid replacements occur at sites which are not effectively neutral, but experience weak selection, in agreement with the nearly-neutral theory [ 25, 26].
This further supports the interpretation that the evolutionary dynamics of at least the mean genotypic values of life-history traits are due to fisheries-induced selection, in agreement with new experimental results using guppies as model species (Van Wijk et al. 2013).
They then met and reviewed their selections for agreement.
Table 6 Feature selection results, Kappa agreement between human annotation and classifiers and accuracy values by classifier Attributes Kappa Acc. Dim.
The loss of genetic variability within populations due to selection is in agreement with quantitative genetic theory (Bulmer, 1971; Visscher et al., 2008).
Finally, we show that the majority of the genome is unconstrained by natural selection currently, in agreement with what has been estimated from phylogenetic methods but in sharp contrast to estimates based on transcriptomics or other high-throughput functional methods.
We can therefore conclude that these markers are probably not functionally important with respect to these selection criteria, in agreement with the lack of statistical association between allelic variation and breeding values for height growth and stem straightness (data not shown).
