Sentence examples for by drift and selection from inspiring English sources

Third, deleterious shorter deletions and rare larger insertions may be fixed by drift and selection in the process of speciation and population differentiation [16].

These low identity and degraded pseudogenes appear not to be functional for antigen variation and likely will be removed from the genome by drift and selection.

Genetic patterns at the contact zone are molded by drift and selection.

We posit that replication of the genetic material is the singular fundamental biological process and that replication with an error rate below a certain threshold both enables and necessitates evolution by drift and selection.

The significance of neurogenetic genes in changing activity and response behaviors across a relatively short evolutionary time period may also relate to how behaviors involved in premating isolation [ 51– 53] can swiftly and easily develop in a population by drift and selection.

In the results we divided the 28 TEs into: one group of 11 TEs with large differences in frequencies between the slopes, which we considered as putatively adaptive caused by natural selection, and to a second group of 14 TEs, which have small or no differences at all between the slopes, which may be caused by drift and weak selection and will be also temporary.

We tested the null hypothesis that FST is driven purely by genetic drift against the alternative hypothesis that it is driven by genetic drift and selection.

For each SNP, we tested the null hypothesis that FST was driven purely by genetic drift against the alternative hypothesis that it was driven by genetic drift and selection.

Simply put, the nearly neutral theory posits that there exists a significant class of alleles that are sufficiently weakly selected such that the evolutionary dynamics are governed by both drift and selection.

Interspecific differentiation of expression may be affected by genetic drift and selection [ 50].

In our experiment, the differences in allele frequencies between the two lines could be driven by genetic drift and selection.
