Sentence examples for conditions of selection from inspiring English sources

The other point that can be made from this observation is that, under the right conditions of selection, recessive mutations due to loss of existing genetics materials are sufficiently common that they can be repeatedly obtained in completely independent populations.
It was assumed that, under the conditions of selection, the frequency of a beneficial allele rises and the allele is driven to fixation within a short period of time in a random-mating population of constant size.
To know whether this selective growth is sufficient will require knowing the formation rate of each mutant type under nonselective conditions and the growth rate of each single and doubly mutant cell type under conditions of selection.
In pilot experiments all four modified inteins showed high splicing efficiency, both in E. coli and yeast, and in yeast the proteins within the excised inteins were active and enabled growth under conditions of selection.
Under conditions of domestication, species can diverge to become very noticeably different, and reproduce for scores of generations under very divergent conditions of selection, yet they do not become infertile with one another.
