Sentence examples for be maintained by selection from inspiring English sources

For instance, it is still unclear if and how alternative splicing can be maintained by selection, or if it is just a transient state before the fixation of a new selectively neutral transcript form by genetic drift.

It follows that unlike in the diploid case, cis-regulated alternative splicing cannot be maintained by selection alone, and that any observed polymorphism for alternative splicing should only be transient.

From equation (1), we find that the conditions under which alternative splicing can be maintained by selection

In contrast, coincidence between cline centres is expected to be maintained by selection against hybrids.

It implies that the length of sequence (coding regions) that can be maintained by selection is set by the mutation rate.

The fusion is thought to be maintained by selection because it facilitates a functional interaction between proteins, such as the kinetic coupling of consecutive enzymes in a pathway.

Thus, if the duplication has been maintained by selection, control of replication may not be the singular or primary selective driving force.

Despite the widespread occurrence of multiple ornaments, and the theoretical interest in how they are maintained by selection, there have been few experimental studies of the phenomenon.

The dearth of pseudogenes suggests that sequence clusters are maintained by selection for high gene-copy number, perhaps due to selection for high expression rates.

In the actual data we observed 599, and we conclude that either there was gene flow more recently than what is implied by the high divergence under the simple model of splitting or polymorphisms were maintained by selection.

These genes show substantially higher values of Tajima's D statistic24 than random genes (Supplementary Fig. 8), as expected for ancestral polymorphisms, regardless of whether they are maintained by selection.
