Sentence examples for escape drift from inspiring English sources

Deleterious mutations are, by definition, subject to purifying selection, while weakly beneficial mutations are unlikely to be substituted by selection because either they cannot escape drift in small populations or, in large populations, are eliminated in competition with the relatively more abundant class of non-synonymous mutations with larger beneficial effects.

Owing to this clonal interference, many beneficial mutations that escape drift nonetheless will be lost in competition with superior mutations [ 44, 45].

This method identifies contending or fixed beneficial mutations (depending on the details of the particular experiment), as opposed to the full distribution of beneficial mutations, because weakly beneficial mutations that may arise will be comparatively less likely to escape drift.

Although unusual for the chronological duration it lasted (24 generations = 16 days), the synchronicity of the fall and rise of the six populations that transiently crashed is consistent with purely phenotypic acclimation independent of new mutations that would be expected to arise and escape drift at different times.

If the whole mountain caved in on itself, radiation could escape and drift across the region, said Wang Naiyan, former chairman of the China Nuclear Society and a senior researcher on China's nuclear weapons program.

"It's not a good idea to use propane above the first floor of a building," she said, explaining that if a tank is dropped and the valve is broken or leaks, the gas could escape and drift down stairways to the floors below.

Displacement of prevailing lineages on the basis of immune escape (antigenic drift) has been suggested for EV30 as the mechanism to maintain viral circulation levels that increase periodically (12, 17, 18 ).

In spite of the genetic architecture of selfing, however, as shown here, once these mutants escape genetic drift and became established in the resident population [ 70], their fate due to selection would be contingent upon whether the ancestral dioecious population was already adapted to the environment where outcrossing was once limiting to them.

These memories, too, start to escape you, drifting down from your head across your body, buzzing through the leaded muscles that lock you firmly to your seat.

At large selection coefficients, the probability of a mutant allele escaping genetic drift is increased, leading to a larger number of observed fixation events.

For example, clonal interference places a constraint on the speed of adaptive evolution (De Visser et al. 1999) and it affects the magnitude of selection coefficients of mutations escaping genetic drift (Perfeito et al. 2007).
