Sentence examples for impeded selection from inspiring English sources

The qualitative results of impeded selection due to culling still apply, but as degree of resistance declines, selection will be slower and the frequency of the resistance allele will ultimately be higher (to achieve the same degree of overall fitness), provided that degree of resistance is above 0.66 (Figure 3).

This impedes selection of a distinctive brain region devoid of tau ligand binding sites as reference tissue [7, 8].

More recently, two theoretical critiques to Wright's assumption that fitness valleys would impede natural selection have been advanced.

The carrier mobility/lifetime is greatly enhanced because the spin degeneracy of the bands is lifted in DMSs and the unwanted recombinations are impeded by spin selection rules or by low occupancy of states involved in the allowed recombinations[53, 54].

As the probability of a cell acquiring a deleterious mutation was comparable to that of the cell acquiring an advantageous mutation, negative clonal selection impeded the growth of only rare cells within the most aggressive clone, and so failed to impede tumour growth.
