Sentence examples for counteract selection from inspiring English sources

We show by deriving a variance, a coalescent and a harmonic mean population effective size, and with simulations that these landscape dynamics generate repetitive founder effects which counteract selection, thereby decreasing the fixation probability of an advantageous mutant but accelerate fixation when it occurs.

This force may counteract selection for translation efficiency, especially when amino acids with high size/complexity score are concerned.

In our study, heterozygosities were reasonably high (Table S1), but estimated effective population sizes were at levels (43.5 44.3) where drift might counteract selection.

In addition, the response to selection also depends on effective population size, because, in small populations, genetic drift is stronger and can counteract selection.
