Sentence examples for maintenance of variability from inspiring English sources

The maintenance of variability was best explained by the input of new mutations [ 36], or perhaps new epimutations.

One important prediction to emerge from our work is that maintenance of variability in body sizes, particularly the maintenance of large individuals, might serve to reduce the strength of fisheries-induced selection for smaller body size.

An alternative and non mutually-exclusive explanation for the maintenance of variability in behavior-related traits is response to changing environmental conditions (reviewed [ 85]), which is also expected to result in balancing selection regimes.

According to our results (Fig. 4A), immigration from the Atlantic Ocean into the Indo-Pacific region doubles that inferred between the Indian Ocean and the Pacific Ocean whereas scaled immigration rates into the Atlantic Ocean are the lowest, suggesting that immigration is less important for the maintenance of variability in the Atlantic Ocean than in other ocean basins.

Wild relatives represent larger amounts of genetic variability than their domesticated descendants and the maintenance of this variability is of central importance in crop conservation and improvement programs [ 2- 4].

Management and genetic conservation plans require knowledge of spatial genetic structure (SGS) to ensure the long-term maintenance of genetic variability in natural populations.

The maintenance of high variability in olfactory receptors has been observed in humans [20], other primates [46] and mouse [47].

Negative frequency-dependence, which favors rare genotypes, promotes the maintenance of genetic variability and is of interest as a potential explanation for genetic differentiation.

Such an approach was compared for banks with varying proportions of embryos on the basis of the amount of the material to be stored, time for reconstruction, maintenance of genetic variability, and probability of failure during reconstruction.

So far, at least six models have been suggested to explain the maintenance of MHC variability, the two most prominent ones being a) balancing selection and b) the rare allele model [ 25].

Likewise, effective population sizes, which are important for long-term maintenance of genetic variability, could be affected, especially in combination with other documented effects of laboratory-based EDC exposure, such as sex reversal, reduced female fecundity, and alterations in timing of reproduction.
