Sentences with phrase «for phenotypic change»

This substantial input of variation from wild ancestors has provided the raw material for phenotypic change, but unique development and genetic mechanisms may also have assisted the course of artificial selection.

Not exact matches

It has been speculated that such heterogeneous production of signaling molecules could be advantageous for the whole population because it allows for a division of labor between signal producers and non-producers, or because the creation of phenotypic diversification provides greater evolutionary flexibility and enables populations to adapt more rapidly to environmental change.

«Because climate change affects some environmental factors like precipitation and temperature but not others like day length, phenotypic plasticity could allow some species to persist in a habitat despite changing conditions and provide more time for them to evolve and migrate,» says co-author Zachariah Gezon, a Ph.D. student in Ecology and Evolutionary Biology at Dartmouth.

Aneuploidy is responsible for the observed phenotypic changes, as chromosome loss restoring euploidy results in a wild - type phenotype.

We are known for our cutting edge translational approach to research, our customized solutions, the breadth and quality of our work, as well as for our ability to identify statistically relevant phenotypic changes, even early and subtle changes, that help our clients quantify the efficacy of their treatments before they move into the clinic.

This suggests that for the most part the accumulation of DNA gains and losses have had little impact on phenotypic change.

Plant from multiple species, seed sources, and climate zones, particularly from locally - adapted sources Manage to maintain genetic diversity and phenotypic plasticity Create opportunities for rapid natural selection for species with high predicted potential for adverse impacts from climate change (Sturrock et al. 2011; Erickson et al. 2012; Alfaro et al. 2014; FAO 2014) Plant drought tolerant and native species Retain diversity of species and promote legacy trees Manage or restore mosaic (variable pattern of species and ages) and maintain or improve landscape connectivity Plant in asynchronous rotations and manage for diverse age classes Thin, plant, and use prescribed fire to favor species adapted to disturbance (Millar et al. 2007; Vose et al. 2016; Keane et al. forthcoming)

These dynamics are the basis for models that predict the evolution of clade frequencies, as well as broad genetic and phenotypic changes.

The objective was to assess whether the breed retains enough genetic diversity to correct the genotypic and phenotypic abnormalities associated with poor health, to allow for the elimination of deleterious recessive mutations, or to make further phenotypic changes in body structure or coat.

Natural spatial and temporal variability in the pH / pCO2 conditions experienced by marine populations provide the potential for different levels of adaptation (genetic) and acclimatization (phenotypic) to decreased pH and elevated pCO2, emphasizing the importance of understanding physiological variation existing along natural environmental gradients (macrophysiology) in understanding global change impacts [29].

Moreover, for the first time, they show that changes in whole - organism phenotypic responses are accompanied by changes in the expression of genes related to intracellular regulatory processes rather than genes thought to be essential for calcification.

(iii) Can organisms» capacity for phenotypic buffering and adaptation offset the consequences of environmental change?
