Sentence examples for speed of fixation from inspiring English sources

In most evolutionary scenarios the chance and speed of fixation of a beneficial allele is greater if the allele was already present in the population than if it arose through a new mutation (Hermisson and Pennings 2005; Barrett and Schluter 2008).

To evaluate the speed of our fixation methods we measured temporal loss of viability following the addition of fixative.

Differences in time and speed of tissue fixation after biopsy or resection may significantly affect the phosphorylated states of signalling molecules.

Speed of anticipatory fixations did not vary with age.

We observed that the time of appearance of resistant mutations (τup) was correlated with the speed and dynamics of fixation.

Finally, such a mutant may be employed for improving its desirable characteristics through evolutionary engineering methodologies in order to speed the fixation and breeding of the genetic traits with industrial interest.

Both the error rate and the rate of fixation breaks peaked for speeds 6 and 12, suggesting that subjects had greater difficulty categorizing these near boundary stimuli.

Several studies have shown control of this environment through choice of fixation devices can facilitate the speed and manner of callus formation across fractures [15, 16, 17, 18].

Studies directly demonstrating that recombination speeds the fixation of beneficial mutations are rarer, but this has been shown in Drosophila [ 23] and bacterial models [ 24].

The examination of the fixation rates and speed of adaptation discloses the dichotomy exhibited by percolation maps and fractal landscapes.

In the latter, there is a smooth change in the pace of the adaptation process, as the landscapes become more aggregated higher fixation rates and speed of adaptation are obtained.
