Experimental Evolution of Gene Expression and Plasticity in Alternative Selective Regimes by Huang, Yuheng, Agrawal, Aneil F

“…Little is known of how gene expression and its plasticity evolves as populations adapt to different environmental regimes. Expression is expected to evolve…”

The evolution of sex is favoured during adaptation to new environments by Becks, Lutz, Agrawal, Aneil F

“…Both theory and experiments have demonstrated that sex can facilitate adaptation, potentially yielding a group-level advantage to sex. However, it is unclear…”

Inferences about the distribution of dominance drawn from yeast gene knockout data by Agrawal, Aneil F, Whitlock, Michael C

“…Data from several thousand knockout mutations in yeast (Saccharomyces cerevisiae) were used to estimate the distribution of dominance coefficients. We propose…”

The Effect of Sexual Selection on Offspring Fitness Depends on the Nature of Genetic Variation by Long, Tristan A.F., Agrawal, Aneil F., Rowe, Locke

“…Whether the changes brought about by sexual selection are, on the whole, congruent or incongruent with the changes favored by natural selection is a…”

Mutation Load: The Fitness of Individuals in Populations Where Deleterious Alleles Are Abundant by Agrawal, Aneil F, Whitlock, Michael C

“…Many multicellular eukaryotes have reasonably high per-generation mutation rates. Consequently, most populations harbor an abundance of segregating deleterious…”

Population genomics of the facultatively asexual duckweed Spirodela polyrhiza by Ho, Eddie K. H., Bartkowska, Magdalena, Wright, Stephen I., Agrawal, Aneil F.

“…• Clonal propagation allows some plant species to achieve massive population sizes quickly but also reduces the evolutionary independence of different sites in…”

Evidence for elevated mutation rates in low-quality genotypes by Sharp, Nathaniel P, Agrawal, Aneil F

“…The deleterious mutation rate plays a key role in a number of important topics in biology, from mating system evolution to human health. Despite this broad…”

Low Genetic Quality Alters Key Dimensions of the Mutational Spectrum by Sharp, Nathaniel P, Agrawal, Aneil F

“…Mutations affect individual health, population persistence, adaptation, diversification, and genome evolution. There is evidence that the mutation rate varies…”

Species richness and identity both determine the biomass of global reef fish communities by Lefcheck, Jonathan S., Edgar, Graham J., Stuart-Smith, Rick D., Bates, Amanda E., Waldock, Conor, Brandl, Simon J., Kininmonth, Stuart, Ling, Scott D., Duffy, J. Emmett, Rasher, Douglas B., Agrawal, Aneil F.

Estimation of the SNP Mutation Rate in Two Vegetatively Propagating Species of Duckweed by Sandler, George, Bartkowska, Magdalena, Agrawal, Aneil F, Wright, Stephen I

“…Abstract Mutation rate estimates for vegetatively reproducing organisms are rare, despite their frequent occurrence across the tree of life. Here we report…”

Spatial Heterogeneity and the Evolution of Sex in Diploids by Agrawal, Aneil F.

“…Much of the theoretical work on the evolution of sex has focused on the effects of recombination. In diploids, segregation also occurs during sexual…”

Ecological Determinants of Mutation Load and Inbreeding Depression in Subdivided Populations by Agrawal, Aneil F.

“…Population structure can dramatically alter mutation load, but the magnitude and direction of this effect depend on whether selection is soft or hard. The…”

Similarity selection and the evolution of sex: revisiting the red queen by Agrawal, Aneil F

DNA repair pathway choice is influenced by the health of Drosophila melanogaster by Wang, Alethea D, Agrawal, Aneil F

“…In nature, individuals vary tremendously in condition and this may be an important source of variation in mutation rate. Condition is likely to affect cell…”

Remating and sperm competition in replicate populations of Drosophila melanogaster adapted to alternative environments by Arbuthnott, Devin, Agrawal, Aneil F, Rundle, Howard D

“…The prevalence of sexual conflict in nature, as well as the supposedly arbitrary direction of the resulting coevolutionary trajectories, suggests that it may…”

Two Forms of Sexual Dimorphism in Gene Expression in Drosophila melanogaster: Their Coincidence and Evolutionary Genetics by Singh, Amardeep, Agrawal, Aneil F
