Sentence examples for under selective neutrality from inspiring English sources

For this D, application of Jukes-Cantor formula [ 4], (eq. 4.2) produces the following value of the per-site number of nucleotide substitutions per a selectively neutral site: (11) Indeed, under selective neutrality the rate of evolution is equal to mutation rate, so that K1/2, neutral = 6 μτ neutral with I = 4, and τ neutral = ln2/ 8 μ) in this case.

The DoS is expected to be zero under selective neutrality, negative under purifying selection, and positive under positive selection.

Indeed, in the simplest case, some amino acids are permitted at a site (under selective neutrality) and some are forbidden (under strong negative selection) - which would lead to a strong correlation.

We selected 20 autosomal regions (Table S1) that met criteria determined by the need for genetic variation evolving under selective neutrality and therefore influenced by demography alone.

However no values of Tajima's D varied significantly from values expected under selective neutrality, and only 3 of the 14 values of Fu's Fs were statistically significant.

Under selective neutrality, Tajima's D, Fu and Li's D and Fu and Li's F are all expected to equal zero.

A low ratio dN/ dS ≪ 1 indicates strong purifying selection, while genes with dN/ dS ≈ 1 are usually considered to evolve under approximate selective neutrality [ 21].

Values of 0 and 1 for ω represent ideal states of purifying selection and selective neutrality respectively.

Thus, mismatch distribution analyses, under the assumption of selective neutrality, were also used to evaluate possible historical events of population growth and decline [ 47, 48].

Significance values of all statistical tests were computed using the coalescent simulator implemented in DNAsp by comparing estimated values against a distribution generated from 10,000 random samples under the hypothesis of selective neutrality and population equilibrium, with no recombination [ 72].

This was enabled by the revolution in population genetics brought about by coalescence theory (Hudson 1990), which is a powerful tool for looking at the statistical properties of a sample from a population under the hypothesis of selective neutrality.
