Sentence examples for be preserved by selection from inspiring English sources
However, in the case of deleterious mutations, a compensatory mutation may occur that renders the two mutations neutral or beneficial as a pair and causes them to be preserved by selection.
What is notable, then, is that nearly all boundaries in Cryptococcus – relatively weakly and relatively strongly selected – are preserved by selection.
Consequently, both altered copies are preserved by selection since any individual former gene is able to entirely perform their biological function (for review, see [ 29]).
This layer of regulatory control over transcriptional networks is preserved by selection across deep evolutionary time, yet selection pressures on individual miRNA genes in contemporary populations remain poorly characterized in any organism.
Again, the only criteria for such additions to be preserved by natural selection are that they must serve some function, and they must confer an advantage relative to alternatives within the population.
If, instead, it is functionally relevant, its repetitive nature will tend to be preserved by purifying selection [ 29, 30].
The natural prediction of the NI-model is that alternative exons will be preserved by purifying selection after GD events.
If the mostly neutral model is correct, only a small fraction of the evolutionary reservoir created by non-adaptive processes will be preserved by natural selection.
Moreover, using multiple-gene knockout data, we find that functional compensation by duplicate genes for a more severe phenotypic effect tends to be preserved by natural selection for a longer time than that for a less severe effect.
This could possibly be the reason that untranslated TE-exons are preserved by natural selection.
