Sentence examples for for a recent selection from inspiring English sources

For a "recent" selection event in one, but not the other population, the selected region displays lower H' values for that population and higher S2FST as different alleles approach fixation in the two populations (Table 1, Figure 2A).

(For a recent selection see Soler et al. 2008).

Uncovering evidence for recent selection is an additional approach to defining functional human genomic variation.

The first method searched for strong recent selection signatures, for which haplotypes have been driven to complete fixation within each breed [ 13].

In human studies, EHH is useful for detecting recent selection within the last 30,000 years [ 32], and the value of iHS is sensitive to the length of the ancestral haplotypes at each position [ 33].

So far, different statistics have been established to detect different kinds of selection signatures, for instance, extended haplotype homozygosity (EHH; Sabeti et al. 2002) for recent selection and Tajimas DD (Tajima 1989) for relatively ancient selection.

Using the CEPH HapMap data, an EHH test was performed to analyse for signatures of recent selection [ 27].

These findings, based on 4-fold degenerate synonymous sites, largely agree with a recent study by Zeng and Charlesworth (2009), who detect significant evidence for recent selection on 2-fold degenerate synonymous sites using polymorphism data from D. melanogaster.

Because of that, according to the nearly neutral theory of molecular evolution (see [ 41] for a recent review), natural selection is expected to be less efficient to create and/or maintain this sequence motif in the X chromosome.

To test for recent selection events, we used the available Integrated Haplotype Score (iHS) data, which takes into account different measures of haplotype length and composition in each population [86].

At least in domestic animals, the explicit use of the pedigree structure in may be more appropriate to detect genomic regions responsible for recent selection e.g. [ 57, 58].
