Adaptive - radiation studies have focused on resource competition, but enemies drive phenotypic diversity in gall midges

These results imply that predators are driving the evolution of phenotypic diversity in symbiotic defense traits in this system, and that divergence in defensive morphology may provide ecological opportunities that help to fuel the adaptive radiation of this genus of midges on goldenrods.

The identification of large - size individuals among the australopithecines — i.e. hominins commonly presumed to be small - bodied on average — shows also that the available fossil record can be misleading, resulting in an underestimate of the hominin phenotypic diversity in any given period.

Since then, under the combined effects of natural selection and human - driven artificial selection, pigs evolved phenotypic diversity in appearance, fertility, growth, palatability, and local fitness.

Systematic swapping of modular protein domains verifies a mechanism for generation of phenotypic diversity in yeast.

Not exact matches

Our findings show the significance for structural variations on phenotypic diversity and a novel role for HOXB8 in feather formation.

Our findings show that sex can generate phenotypic and genotypic diversity de novo in the pathogenic yeast C. neoformans with implications for other eukaryotic microbes and pathogens, including other fungi and parasites that are common pathogens of humans.

Aneuploidy was also detected in progeny from a-α opposite - sex congenic mating; thus, both homothallic and heterothallic sexual reproduction can generate phenotypic diversity de novo.

The alternative model is that mutations of large phenotypic effect underlie most of these traits in dogs and that the same variants have been transferred to a wide diversity of dog breeds leading to phenotypic diversity from a narrow genetic base [5], [8], [12].

Biochemical analysis of phenotypic diversity associated with mutations in codon 244 of the retinal degeneration slow gene.

Such programs, best undertaken in an adaptive management framework, include, but are not limited to, reducing fire risk; managing forest diseases; improving forest establishment; increasing forest carbon storage; improving water availability and soil quality; improving forest diversity, structure, and resilience; and increasing genetic and phenotypic diversity of forests.

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)

Besides ensuring correct chromosome segregation during the first meiotic division, crossovers create new allele combinations in gametes, thereby increasing genomic diversity, increasing the chance of creating offsprings with better phenotypic fitness, and providing the basis for faster evolution.

Structural rearrangements have long been recognized as an important source of genetic variation, with implications in phenotypic diversity and disease, yet their detailed evolutionary dynamics remain elusive.

The loss of genetic diversity in purebred dogs can be attributed to two major population bottleneck events: the first occurring during domestication; and the second arising from breed formation where the repeated use of popular sires, line breeding, breeding for specific phenotypic traits, and promotion of the breed barrier rule, contributed to overall loss in genetic variation [15 - 19].

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.

A DNA - based assessment of the breed along a number of parameters has confirmed that the breed is greatly lacking in genetic diversity, which may preclude or minimize the ability of breeders to recreate healthier phenotypes from existing genetic stock, to eliminate deleterious mutations, and to add in new phenotypic traits.

Assuming that there is a will to improve the overall health of English bulldogs, the question raised by this study is whether or not there is sufficient genotypic diversity remaining in the breed to allow «reverse genetics» to correct phenotypic abnormalities that have major impacts on health.
