Sentence examples for be under natural selection from inspiring English sources

In D. buzzatii, body size related traits (such as wing length), known to be under natural selection [ 36- 38], are affected by the nature of the breeding substrate [ 21, 39- 41].

Specifically, the property changes that TreeSAAP detected in step 1 of the analysis were correlated with the same properties TreeSAAP detected to be under natural selection throughout mammalian evolution.

In the course of colonization, bacteria may be under natural selection to adapt to their new environments.

We explored two phenotypic traits that may be under natural selection in lizards (coloration and number of throat scales).

The loci that show unusually low or high levels of genetic differentiation are often assumed to be under natural selection [ 64].

While it is, therefore, likely that morphological traits have been, and continue to be, under natural selection, any evolutionary response to selection is contingent on the presence of additive genetic variation underlying observed phenotypic variation.

We evaluated whether human genome sequences of the Japanese population derived from archaic hominins, such as Neanderthal or Denisovan, were under natural selection pressure.

Using this technology, Gilad and colleagues demonstrate that most genes are under natural selection to maintain a constant level of expression, but that a few genes show evidence of species-specific changes.

In the present study, six different statistical methods consisting of four independent codon-based maximum likelihood (CML) methods, one hierarchical Bayesian (HB) method and one branch-site (BS) method, were employed to determine if each amino acid site of A/H7N9 virus is under natural selection pressure.

Most probably, these cells constitute a suppressor strain where a second mutation occurred restoring the original phenotype, by reverting the effect of CCTαG346E mutation, and are under natural selection when growth occur over long periods.
