Sentence examples for sweep model from inspiring English sources

Finally, we highlight a growing need for detecting adaptations that did not follow the classical sweep model and for incorporating new sources of genetic evidence such as information from ancient DNA.

A challenge in the use of H2/H1 is that its range depends on the associated value of H12, so that equal H2/H1 values might provide different levels of support for a soft sweep model at different values of H12.

This complex model of 'multiallelic' directional selection seems to better fit the patterns of NAT2 diversity observed in present-day populations than the standard 'hard sweep' model which assumes the rapid fixation of a single newly arisen advantageous mutation [10].

To further assess the possibility of a selective sweep at this locus, sequencing a larger region and distinguishing ancestral and derived alleles would allow the spatial distribution of allele frequencies to be assessed for the pattern expected under a selective sweep model [35] using more advanced methods such as that of Kim and Stephan [36].

Support for the sweep model is reported as the log-likelihood ratio of the sweep model to the background SFS.

M1, neutral model; M2, bottleneck model; M3, selective sweep model; NS, non-significant.

The simplest cyclotron sweep models result in convection-dominated transport, contradicting observations.

These results are evaluated in relation to expectations of the background selection and selective sweep models.

For instance, consider a period of neutral evolution beginning with a genotypically homogenous population (e.g., following a sweep), modeling mutation as a Poisson process.

To better discriminate the bottleneck and the sweep models, departure from the M1 model was tested individually for each locus (called M3 model).

Polygenic models of adaptation have been under-represented in population genetics, a field that has tended to favour classical sweep models focussing on shifts towards fixation of beneficial alleles at one or a few loci (Pritchard et al. 2010).
