Sentence examples for a single selection pressure from inspiring English sources

The study of closely related species has shown how a single selection pressure, e.g. coloniality or offspring mobility, can markedly impact recognition abilities.

When a gene is highly transcribed and regulated by a single promoter, the selection pressure prevents any considerable change in the promoter's structure to provide for its effective binding to the polymerase.

Since such an inhibitory mechanism is not able to separate the DNA-binding and activation domains present in a single ARF, we hypothesize that a strong selection pressure on domain I of Aux/IAAs for the efficient recruitment of transcriptional co-repressors could have been a feature of Aux/IAA evolution after the appearance of canonical Q-rich ARFs.

The study of endogamy in cattle is extremely important, particularly due to the widespread use of artificial insemination, which allows a high selection pressure and rapid genetic gain, resulting in thousands of descendants from one single sire.

Thus, from a single instance of implementing this methodology, one can at best learn how notochord stiffness might evolve under a given selection pressure starting from given initial conditions.

One explanation for such a threshold level may be a selection pressure to retain stabile conformations.

Whether a common selection pressure balances diversity at both loci remains to be established.

A positive selection pressure for the V3 diversity can be the humoral immunity.

Modelling demonstrates that this sequence of evolutionary events requires a strong selection pressure.

Alternatively, there may have been a natural selection pressure that strongly favoured the two-row condition.

A negative selection pressure has been discussed for non-lethal disorders or rare inherited syndromes.
