Sentence examples for strength of drift from inspiring English sources

In addition, deleterious mutations in immunologically-relevant genomic DNA can become fixed in small isolated populations given the increasing strength of drift over selection and the fact that selection may be reduced if the pathogenicity of the island environment is indeed reduced.

Heterosis quantifies the relative strength of drift among natural populations using mean fitness within populations as the frame of reference.

In other words, this hybrid approach of assuming a prior based on a strain's genotype, and then fitting a diffusion coefficient to summarize strength of drift, does not seem to be a pure measure of drift.

A model that could give rise to more rapid RI for small populations is based on founder events or peak shifts, where small founder populations split and become isolated (Lande 1979, 1985; Barton and Charlesworth 1984; Barton and Rouhani 1987); the strength of drift is larger in small populations, allowing them to more easily pass through fitness valleys.

Contrary to the predictions of this model, the strength of drift is "negatively" correlated with genome size in Bacteria (Kuo et al. 2009; Novichkov et al. 2009), with those bacteria the lifestyles of which cause the most dramatic reductions in effective population size having the most reduced genomes (Moran and Plague 2004; Nakabachi et al. 2006).

A reliable indication of the occurrence and strength of drifting snow events can be determined even if the absolute accuracy is difficult to quantify.

The strength of genetic drift is inversely proportional to Ne and hence drift is a more important force in small populations [ 17].

In other words, we cannot absorb the effects of interference into a single modified strength of genetic drift.

The strength of genetic drift appears as a prefactor of S λ({ z ρ}) in the exponent.

The strength of genetic drift during the domestication bottleneck is determined by its duration and the effective population size [ 13].

Accordingly, the strength of genetic drift is proportional to the degree of host-endosymbiont interdependency, with facultative endosymbionts being less affected than obligatory endosymbionts.
