Sentence examples similar to a beneficial selection from inspiring English sources

We found that most students wrote down words associated with 1) the four principles of natural selection, including 'survival of the fittest', 'variation', 'reproduction', and 'inheritance', 2) the result of natural selection, including 'change'evolution'on'descentent with modification', and 3) beneficial selection, including 'adaptation' and 'advancement'advancement

Second, in our framework, s b denotes the (beneficial) selection coefficient for heterozygotes.

On the other hand, if fitness differences between mutant and wild type are sufficiently large, stochastic fluctuations are overruled by deterministic selective forces which can lead to accelerated fixation of a beneficial mutant (positive selection), or its rapid removal as a consequence of strong selective constraints (purifying selection).

Together, these results indicate that resistance should not spread within a microbial population under group-beneficial selection, even if grown in a viscous or spatially structured environment, as long as the colony-to-colony distance is smaller than the diffusion distance of secreted goods.

To induce production of LasB in the group-beneficial selection, the resistant mimic was engineered to constitutively express lasB (see Supplementary Text and Supplementary Figures 4 and 5, Supporting Information).

The importance of this influence is illustrated by the unique example of the ovary-biased genes that apparently do not rely on the activation/repression mechanism and strongly accumulate on the X chromosome in perfect agreement with the female-beneficial selection model [ 7, 29].

"That's incredibly fast". Under natural selection, a beneficial gene may take hundreds of generations to reach high frequencies in a population, he added.

Hill-Robertson effects include hitchhiking [ 36], fixation of sites linked to a beneficial mutation, and background selection [ 37] or loss of variation linked to a deleterious mutation, which lead to reduced effective population size for a genomic region with a low recombination rate.

In general, the frequency of a beneficial trait that is under selection will increase steadily in the population toward some arbitrary value, while that of a neutral trait will drift randomly from generation to generation, eventually becoming fixed at 100% or disappearing altogether (Holland and Holland 1990).

Artificial selection of a beneficial mutation will lead to an elevated frequency in a population.

Different statistics pick up different patterns of variation left by selection of a beneficial mutation.
