Sentence examples for are counterselected during evolution from inspiring English sources

Orientation biases were previously observed for endogenous retroviruses [31], [32], indicating that gene-inactivating integration events are counterselected during evolution of the host genomes.

Our work shows for the first time that overlap between protein coding genes, although widespread, is counterselected during Metazoan evolution.

Such genes might be counterselected during growth and result in problems.

As a consequence, high expressing lines are counterselected and tuber carotenoid levels show only modest (up to 3-fold) increases.

Given the evolution of faster replicating parasites, units of replication that rely on helpers for survival, such as the master sequence, are counterselected and go extinct (as explained above).

However such virulent T. gondii strains are counterselected by acute lethality in less resistant mice, while less resistant mice are better hosts for less virulent T. gondii strains.

Either mixed genotypes are counterselected (intermediate stages, Figure 10B) may not be evolutionarily successful or the turnover (birth and extinction) of rDNA arrays in genomes is extremely fast so intermediate genotypes are short-lived and escape detection.

The true proportion of metabolic gene knock-outs in colony morphology variants is probably even higher because a library was screened that had been counterselected for auxotrophic mutants.

E. coli donors were counterselected by the addition of D-cycloserine (250  μg ml−1) to the media.

Indeed, if a higher value is associated with stronger deleterious effects, the stronger distorters would not necessarily have a greater advantage and could even be counterselected.

As expected under this selective pressure, genes with numerous and/or closely spaced histidine codons have evidently been counterselected in the genome of P. carbinolicus.
