Sentence examples for reduced constraints from inspiring English sources

This way, the combined action of mutation, uptake bias and reduced constraints in some genomic regions could be sufficient for DUESs to gradually accumulate in susceptible parts the genome and no additional function is needed.

Although disordered regions showed reduced constraints on amino acid changing polymorphisms relative to structured proteins, the rate of amino acid polymorphism was not dramatically different.

For instance, segmental duplications may translocate the derived copy to a different regulatory environment where it may evolve under different or reduced constraints [ 8].

A recent study shows that olfactory receptors are significantly over-represented in human-specific pseudogenes [ 34], providing further evidence of reduced constraints.

In this cluster, which contains genes involved in perception of smell, the coding bases evolve rapidly in mammals suggesting reduced constraints on coding base-positions.

However, relative to the state of the genes before the duplication, there is significant relaxation of selective pressure on at least some of the paralogs, suggesting reduced constraints.

This finding might potentially be attributable either to positive selection or to a reduced constraint level on these genes.

Some Lhx proteins show long branch lengths on phylogenetic trees, suggesting that these subfamily members may be experiencing reduced constraint and/or positive selection.

In principle, a major reason for a change in rate associated with a particular phenotype is an altered selective regime occurring under that phenotype, such as positive selection or reduced constraint.

It has been postulated that gene duplications safeguard against deleterious mutations [ 28], and allow more rapid rates of evolution within coding sequences [ 29], as one gene copy retains gene function whilst the other has reduced constraint to accrue new mutations.

Clusters are good in any field because they boost productivity and innovation, and cluster policy seeks to reduce constraints and encourage externalities to raise the productivity of competition.There is limited experience in policy toward clusters, which sit in between policies aimed at the general business environment and policies targeted at creating incentives for individual firms.
