Sentence examples for by different selective pressures from inspiring English sources
Unlike site model, switching models allow each codon site to change the selective regime, and thus be affected by different selective pressures at different time points.
These results imply that the number of RP genes affected by different selective pressures increased gradually during the evolutionary process from prokaryote to human.
The whole body of data reported above suggests that the fusion(s) of histidine biosynthetic genes has been driven by different selective pressures.
Thus, in different species, the distinction of own group (or unit) vs. neighboring group (or unit) members may be driven by different selective pressures.
These recognition systems have evolved independently for >500 Mya, presumably shaped by different selective pressures from the environment, self-tolerance, and microorganisms.
A possible explanation for this phenomenon is that exon Alu retention is under similar selective pressures on all chromosomes, while the intron Alu densities are controlled by different selective pressures.
However the division happens, eventually the subpopulations evolve genetic differences (perhaps triggered by the different selective pressures in their separate environments) and become discrete species, unable to mate with one another and reunite their genes.
This could be caused by numerous horizontal transfers or by distinctly different selective pressures on these genes, such as if some proteins are not actually SAICAR synthetases or have a second activity in addition to SAICAR synthetase.
By applying different selective pressures to the library, it is now possible to identify genes critical for survival and growth under different conditions.
Disease transmission during mating provides a connection between reproduction and immunity, where sexually transmitted diseases (STDs) can affect fitness of individuals by imposing different selective pressures on their hosts.
They inferred that these compositional differences reflect different selective pressures related to preferred prey.
