The phrase "a weaker selection" is correct and usable in written English.
It can be used when discussing choices or options that are not as strong or effective as others.
Example: "In this round of the competition, the judges were disappointed with a weaker selection of performances compared to previous years."
Alternatives: "a less robust choice" or "a subpar option".
These reviewers are finding that Android has a weaker selection of applications than the iPhone not just because some of their favorite apps aren't there, but because actually browsing the Market just isn't as enjoyable as what Apple's iTunes offers.
As previously described by Mehlotra et al. [9], we did not observe a strong reduction of heterozygosity in the CQ resistant parasite population, underlining that drug pressure from CQ treatment exerts a weaker selection on Pfmdr-1 than on Pfcrt.
This might have resulted in a weaker selection pressure on individual positions of the PAM than previously thought.
A weaker selection pressure by natural enemies could explain why these particular traits evolved different levels of plasticity.
In the simulations we use two different values for σ, σ=0.4, which corresponds to a hard environment, and σ=0.6, which corresponds to a weaker selection.
The higher effective Nc in L. cuprina (43.81) than D. melanogaster (40.89) suggests a weaker selection constraint on codon usage in L. cuprina, at least for these highly conserved genes.
Firstly, the fitness uniform selection strategy (FUSS) with a weak selection pressure is incorporated into the standard PSO.
The finding of fruit weight QTLs, and miRNA172s, and their target genes from comparisons between small-fruited wild apples and large-fruited cultivars helped explain why a weak selection in a highly heterozygous perennial crop can still yield favorable large fruits.
a Weak selection (simulation B) and b strong selection (simulation C).
Yet even synonymous mutations are not entirely neutral: there is a weak selection for synonymous codons that are more common [1].
In addition, Henter [40] suggested other possibilities, such as (1) a different genetic control for the trait for both sexes, (2) that the fitness reduction was due to the loss of overdominant heterozygotes under inbreeding or (3) a weak selection for the trait in the field.
