Sentence examples for fixation of a single from inspiring English sources

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].

The probability of fixation of a single copy of allele 2 is u(s) [ 26].

These differences could have evolved through multiple speciation events, each involving the fixation of a single chromosomal rearrangement.

In small populations the fixation of a single retroposition event is much more likely than in large populations [ 53].

The fixation of a single haplotype in the Apennine Peninsula prevents conclusions about the intensity of past gene flow between this population and Eastern European population.

Although our research question was highly specialized, i.e. fixation of a single type of TKA, we were still able to include 3 studies.

He became disenchanted with communism and was deeply suspicious of any political philosophy that encouraged fixation on a single goal without any regard for the grim consequences this could have.

While frequency-dependent selection should impede fixation of a single-sex locus through the advantage of rare sex alleles on lowering the production of diploid males, the strength of frequency-dependent selection on a given locus may be much weaker under ml-CSD.

On the other hand, fixation or near-fixation of a single ancestral genetic background occurred throughout most of the genome in all the evolved lines; moreover, patterns of fixation were qualitatively similar in all three evolved lines.

If the same total progress toward the optimum can be made by the fixation of either a single allele of large effect or many alleles with small effects, adaptation will be faster in the former case, because selection on the large alleles is more effective (Gomulkiewicz et al. 2010; for the same result in a different context, see also Gavrilets et al. 2007; Rettelbach et al. 2011).

Ohtsuki et al. [ 31] have shown that if they use the so called "death-birth" update rule (details see below) then selection favours cooperation (i.e. the average fixation probability of a single cooperator is higher than the fixation probability of a neutral mutant) in the PD game if the b/ c ratio exceeds the average number of neighbours in the network (⟨ k⟩), that is, if b/c > ⟨ k⟩.
