Sentence examples for measuring the selection from inspiring English sources

This can be evaluated by measuring the selection gradient (partial regression of fitness on character state) and calculating the distance between the optimal phenotype and the population mean, in units of phenotypic standard deviations.

In four of the five lines where we sequenced isolates from the midpoint populations, we found genotypes that were no longer present in the endpoint population, which we refer to as 'lost.' Furthermore, from measuring the selection coefficients of one of these lost individuals we found that mutations with relatively large selection coefficients can be lost.

The ancestral and derived haplotypes were compared using integrated Haplotype Score (iHS test) to measure the selection strength of each locus (Sabeti et al., 2006; Voight et al., 2006).

We used two values of Long Range Haplotype analysis to measure the selection, EHH and REHH [79].

To measure the selection response, flies were collected as 0 72 hour embryos and split during early larval stages into replicates raised on media with or without geldanamycin, and adults were analyzed for SC bristle number.

In addition we measured the selection pressures operating on individual genes.

Notice that we measure the selection on the modifier between generations 1000 and 2000 (see section methods).

We have measured the selection coefficient for these haplotypes by estimating sup, which ranges between 0.015 and 0.077.

Because φ i measures the selection (preference of the host machinery) in favor of the U-ending codons, it is expected to be positively correlated with PU. i.
