Sentence examples for by selection for alternative from inspiring English sources

Accumulation of GC sites might have been driven by selection for alternative splicing.

Here reproductive isolation can be achieved in the absence of intrinsic barriers to gene flow, by means of divergent selection for alternative environmental conditions or food resources [ 22- 26].

An alternative or additional possibility is that variability is driven by selection for resistance to bacteriophages that infect xanthomonads.

Furthermore, positive selection for two alternative proteins coded by the same gene can result in balancing selection at the DNA level (i.e. heterozygote advantage or frequency-dependent selection) (Bamshad and Wooding 2003; Nielsen 2005; Sabeti et al. 2006).

This was done by alternative selection for binding to the antigen at pH 7.4 and non- (or reduced) binding at pH 6.0 (Fig. 2A and Supporting information, Fig. S1, for all selection rounds).

The variation was tiny, and suggests that the Y chromosome has been pared down to its bare essentials by "purifying selection"An alternative explanation for the low genetic variation of Y chromosomes is that a minority of men had a high proportion of children, passing on fewer Y chromosome variants to each successive generation.

The alternative hypothesis that the higher sequence divergence in these regions is caused by positive selection for single nucleotide mutations was not supported by our analysis.

The proposed method enables robust decisions for alternative selection by making use of all available information, managing conflicting interests and presenting performance targets and trade-offs.

The number of data points limited our choice for alternative variables indicating strength of sexual selection.

It follows that unlike in the diploid case, cis-regulated alternative splicing cannot be maintained by selection alone, and that any observed polymorphism for alternative splicing should only be transient.

MAFU establishes a fuzzy set for including stakeholder preferences, develops system-wide multiplicative multi-attribute utility functions for each alternative and generates a tradespace for alternative selection.
