Although most of them have deleterious effects on fitness [1] [3], natural selection increases the representation of those having beneficial effects, which can become fixed in a population.
Pooling RNA from several animals potentially increases the representation of transcripts common to all animals but might decrease the ability to detect transcripts that are unique to one animal.
In control normalization, YRI1 as control increases the representation of these regions in UG1.
Furthermore, the discovery of 64 NTUs with FPMK ≥ 10 in supercontigs previously annotated as containing no protein-encoding genes increases the representation of our data set.
It is tempting to speculate that ACh increases the representation of stimuli at the current attentional focus, and protects it against interference from competing stimuli, thus resulting in reduced distractibility.
It has been reported that the use of three different restriction enzymes resulted in a more accurate coverage of the genomes, since the different GC contents of their recognition sites increases the representation of a higher number of genomic regions [ 35].
