The phrase "a lower selection" is correct and usable in written English.
It can be used when referring to a choice or option that is of lesser quality, rank, or value compared to others.
Example: "In the survey, participants were given a lower selection of options to choose from, which limited their choices."
Alternatives: "a lesser option" or "an inferior choice".
Of the class of indexes that meets the same restriction, it is preferable to choose the index that requires the least selection intensity because it is easier to achieve the selection goal with the use of an index that requires a lower selection intensity than a higher selection intensity.
Generally, a lower selection pressure indicates a higher evolutionary rate.
The measured costs are however lower than for 200 μM IPTG, which predicts a lower selection coefficient.
This durability could be explained by the smaller effects of partial resistance that result in a lower selection pressure on the pathogen and/or its presumed broader spectrum.
If resistance to oseltamivir was increased, both prophylaxis strategies became less efficacious and efficient, but postexposure prophylaxis posed a lower selection pressure for resistant virus strains.
Meanwhile, the TFs which are specific to plants, for example VOZ and Whirly experienced a lower selection pressure, had more of the variation in the paper mulberry.
This region is also apparently a region with lower selection on the synteny – this is the location of the inversion breakpoint in A. gambiae, and is also the location where other genes have interposed into the cluster, such as CG15594 and CG15597 in D. melanogaster.
The vg5 was 5% higher for the scheme with a low heritability, because of lower selection accuracy.
In addition, letting the experiment run for a greater number of generations at this lower selection pressure increases the maximum power attained.
Overwintering diapause results in recurrent population size bottlenecks, particularly for males, and thus in a lower effective population size Ne, and lower selection efficiency in removing slightly deleterious nonsynonymous mutations, as indicated by its genome-wide higher dN/ dS.
It has been proposed that solvent exposed amino acids have a lower purifying selection and for this reason could vary more easily.
