Data from: Test of synergistic interactions among deleterious mutations in bacteria
- 负责人：
- DOI：
- doi:10.5061/dryad.rg8mb
- 摘要：
- and combined effects on fitness were determined. Several pairs exhibit significant interactions for fitness, but they are antagonistic as often as they are synergisti
Data from: Diverse phenotypic and genetic responses to short-term selection in evolving Escherichia coli populations
- 负责人：
- DOI：
- doi:10.5061/dryad.f7p18
- 摘要：
- on of Escherichia coli. Whole-genome sequencing was able to identify the majority of beneficial mutations. In contrast to previous studies, we find diverse fitness effect
Data from: Benefit of transferred mutations is better predicted by the fitness of recipients than by their ecological or genetic relatedness
- 负责人：
- DOI：
- doi:10.5061/dryad.t60n5
- 摘要：
- with the genomes of diverse natural isolates of the same species. We find that the fitness effect of transferred mutations depends weakly on the geneti
Data from: Evolution of drift robustness in small populations
- 负责人：

- DOI：
- doi:10.5061/dryad.nr780
- 摘要：
- Most mutations are deleterious and cause a reduction in population fitness known as the mutational load. In small populations, weakened selection agains
Data from: The basis of antagonistic pleiotropy in hfq mutations that have opposite effects on fitness at slow and fast growth rates
- 负责人：
- DOI：
- doi:10.5061/dryad.5bd50
- 摘要：
- growth rates. The fitness of hfq mutations in Escherichia coli affecting the RNA chaperone involved in small-RNA regulation is remarkably sensiti
Data from: The mutational decay of male-male and hermaphrodite-hermaphrodite competitive fitness in the androdioecious nematode C. elegans
- 负责人：
- DOI：
- doi:10.5061/dryad.2ng4k
- 摘要：
- estimates of the average selection coefficient against mutations affecting hermaphrodite competitive fitness agree to within two-fold, 0.33%-0.5%.
Data from: Abiotic stress does not magnify the deleterious effects of spontaneous mutations
- 负责人：
- DOI：
- doi:10.5061/dryad.vq452
- 摘要：
- kely reflects the very low starting fitness of some low-fitness MA lines, the potential for cross-stress responses and the context dependence of mutati
Data from: Sexual selection can remove an experimentally induced mutation load
- 负责人：
- DOI：
- doi:10.5061/dryad.7p79h
- 摘要：
- Sexual selection is argued to be important for the removal of deleterious mutations, promoting population fitness, accelerating adaptation

- 摘要：
- ) to mutation effects on fitness implies spatial and/or temporal variation in selection on new mutations and could contribute to the maintenance
Data from: Negative epistasis between beneficial mutations in an evolving bacterial population

- DOI：
- doi:10.5061/dryad.5rv40
- 摘要：
- pread, but they have rarely considered beneficial mutations. We analyzed the effects of epistasis on fitness for the first five mutations
