Entropic contribution to phenotype fitness

چکیده
All possible phenotypes are not equally accessible to evolving populations. In fact, only of large size, i.e. those resulting from many different genotypes, found in populations sequences, presumably because they easier discover and maintain. Genotypes that map these usually form mostly connected genotype networks percolate the space thus guaranteeing access a set alternative phenotypes. Within given environment, where specific phenotypic traits become relevant for adaptation, replicative ability phenotype its overall fitness (in competition experiments with phenotypes) can be estimated. Two primary questions arise: how do reproductive capability topology network affect phenotype? And, assuming evolution is able phenotypes, what range unattainable values? order address questions, we quantify adaptive advantage varying size spectral radius two-peak landscape. We derive analytical relationships between three variables (size, topology, ability) which then tested through analysis genotype-phenotype maps simulations population dynamics on such maps. Finally, analytically show fraction attainable decreases length genotype, though absolute number increases. The fact most visible very likely forbids attainment highest peak Nevertheless, our results indicate relative loss due this limited accessibility largely inconsequential adaptation.

Group Selection and Contribution of Minority Variants during Virus Adaptation Determines Virus Fitness and Phenotype
Understanding how a pathogen colonizes and adapts to a new host environment is a primary aim in studying emerging infectious diseases. Adaptive mutations arise among the thousands of variants generated during RNA virus infection, and identifying these variants will shed light onto how changes in tropism and species jumps can occur. Here, we adapted Coxsackie virus B3 to a highly permissive and ...
متن کاملSusceptibility of the male fitness phenotype to spontaneous mutation.
Adult reproductive success can account for a large fraction of male fitness, however, we know relatively little about the susceptibility of reproductive traits to mutation-accumulation (MA). Estimates of the mutational rate of decline for adult fitness and its components are controversial in Drosophila melanogaster, and post-copulatory performance has not been examined. We therefore separately ...

UNLABELLED Endosymbiotic bacteria of the genus Wolbachia represent the most successful symbiotic bacteria in the terrestrial ecosystem. The success of Wolbachia has been ascribed to its remarkable phenotypic effects on host reproduction, such as cytoplasmic incompatibility, whereby maternally inherited bacteria can spread in their host populations at the expense of their host's fitness. Meanwhi...
متن کاملGenetic Factors in Systemic Lupus Erythematosus: Contribution to Disease Phenotype
Genetic factors exert an important role in determining Systemic Lupus Erythematosus (SLE) susceptibility, interplaying with environmental factors. Several genetic studies in various SLE populations have identified numerous susceptibility loci. From a clinical point of view, SLE is characterized by a great heterogeneity in terms of clinical and laboratory manifestations. As widely demonstrated, ...
