Sentence examples for be under higher selective from inspiring English sources
Stronger binding sites could be under higher selective pressure, since they are more likely to have a vital function.
This re-evaluation could be performed using a larger set of molecular markers, particularly SNPs, that occur mainly in effector sequences, which should be under higher selective pressure.
In contrast mothers are likely to be under high selective pressure through parent-offspring conflict and the costs of misdirected parental care.
A large fraction of genes was found to be under high selective constraint, as most of the expressed genes appeared to be involved in developmental gene regulation.
Some K-Channels have been suggested to be under high selective pressure in songbirds, based on dN/dS ratios in comparison with chicken [ 6, 12].
In such species that lack the opportunity to obtain extra-pair fertilizations, mate choice may therefore be under high selective pressure.
To further determine whether additional K-Channel genes might also be under high selective pressure, we first compiled dN/dS ratios for all 100 K-Channel genes that had orthologs in chicken based on an Ensembl summary of gene orthologs.
Nevertheless, the moderate increase of conservation at the long fraction RNA loci suggests that non-tRNA sequences are under higher selective pressure than their proximal regions.
(c) Genes that remain GCO have on average significantly lower Ka/Ks ratio than the nGCO ones, indicating that they are under higher selective pressure (Fig. 2).
If the evolutionary rate had been a major contributing factor for the differences in the numbers of CNSs, the lineage-specific genes should also follow the same pattern as CNSs (unless the lineage-specific genes are under higher selective constraint).
