Sentence examples for mutational input of from inspiring English sources

More generally, these could be evolving, co-dependent variables in their own right, and this could be shown by taking a 'closed model' approach [41] that allows such characteristics to emerge from concrete population processes such as the pattern of dispersal and the mutational input of novel genetic material.

Whenever genetic variation for functional traits is determined solely by a mutational input of beneficial alleles (as opposed to standing levels of genetic variation), as it is the case for the majority of the investigated host traits in A. millepora, the rate of environmental change to which a population might be able to adapt to might be as low as one percent per generation [52], [53].

Our results suggest that this difference between prokaryotes and eukaryotes is due in large part to the mutational input of insertions and deletions to a genome.

The alignments allowed us to infer the exact boundaries and ancestral state of indels within these noncoding regions, which together provide robust estimates of the mutational input of base pair- to kilobase-sized insertions and deletions to these genomes.

Such arguments about the role of sexual selection in the evolution of outcrossing rates are limited to populations that segregate standing genetic diversity or that are subject to the recurrent mutational input of deleterious alleles [ 31, 38- 40].

The mutational input of insertions and deletions to a genome, as measured either by the number of events or the total length of DNA segments, is inherently biased toward deletions across a wide range of taxonomic groups representing the three domains of life.

By taking advantage of the large collection of genome sequences available, we examined a diverse set of lineages to directly compare the impact of mutational input on genome evolution across the domains of life.

Thus, mutational input for viability traits may increase as a direct consequence of intense sperm competition, and this may suffice to maintain genetic variability in fitness.

This difference between the mutational input to a genome and its overall base composition suggests the action of natural selection.

In contrast, experiments with populations without initial standing genetic diversity give an unbiased picture of the genetics of fitness components, despite history and environmental context, as they depend on mutational input for evolution [ 26, 27].

To ascertain the mutational input to a genome, the present study focused on small indels occurring in noncoding regions; however, there are several classes of large-scale mutations that can contribute to genome size evolution.
