Sentence examples for variations that maintain from inspiring English sources

The proposed RNA secondary structures, based on RNAfold and multiple alignment covariation analysis, highlight compensatory variations that maintain hairpin structures and, for sRk28, a potential pseudoknot structure.

The lack of a heredity mechanism was one of the greatest shortcomings for the Origin, one that would not be overcome for 70 years until the discovery of genetics and understanding of sources of hereditary variation and mechanisms that maintain variation within populations (Provine 1971).

The higher number of fixed alleles in non-neutral SSRs could be explained by temporal variation of external factors, generating selection pressures that maintain variation within populations [ 52].

An open question regarding such GS variation concerns the mechanisms that maintain extra DNA within species.

Balancing selection and antagonistic pleiotropy are commonly dismissed as population genetic forces that maintain variation across many loci, because of a perceived lack of evidence, but studies drawing on human genomic variation have uncovered a large suite of apparent cases over the past 10 years (Andrés et al. 2009; Table 1).

In this paper, we show that Lehmann and colleagues reach different conclusions than we do because they make different assumptions, both about the processes that maintain variation among groups and about the selective processes that lead to the spread of group beneficial variants.

Identifying the underlying genes and environmental contexts that affect aggressive behavior is important for understanding the evolutionary forces that maintain variation for aggressive behavior in natural populations, and to develop therapeutic interventions to modulate extreme levels of aggressive behavior in humans.

In addition to Boyd's 'homeostatic' mechanisms we need to recognize 'heterostatic' mechanisms that maintain species variation.

These data highlight extensive levels of genetic diversity, but raise questions about the mechanisms that maintain such variation.

The factors that maintain this variation in wild populations remain to be established.

The authors conclude that the relationship between field fitness and observed glucosinolate genotype frequencies is due to fluctuating selection pressures that maintain genetic variation in nature.
