The Evolution of Sex Is Favoured During Adaptation to New Environments
In experiments with a facultatively sexual rotifer, populations adapting to novel environments evolve higher rates of sex because sexual mixing quickly assembles well-adapted genotypes.
Correlations between sex rate estimates and fitness across predominantly parthenogenetic flatworm populations
TLDR
One explanation for the success of sexual reproduction is that sex increases the efficacy of natural selection, and adaptation to changing environments is accelerated and population mean fitness will increase.
Oogamy: Inventing the Sexes
Evolutionary biology: Why reproduction often takes two
On the face of it, self-fertilization is the efficient way to breed: compared with outcrossing, there's usually much less fuss, for a start. So why isn't reproduction by selfing far more prevalent
Why Sex Is Good: On Fungi and Beyond
TLDR
This chapter discusses aspects of fungal biology that are relevant for an understanding of the occurrence of sex in fungi and the main advantages of sexual reproduction compared to asexuality are likely to be acceleration of adaptive evolution and more efficient elimination of deleterious mutations.
The kin structure of sexual interactions

TLDR
It is concluded that systematically analysing the kin structure of sexual interactions helps illuminate their evolution and predicts optimal sex ratios and potential conflicts over sex ratio within social groups and individuals.
Fitness-Associated Sexual Reproduction in a Filamentous Fungus
Transitions to asexuality and evolution of gene expression in Artemia brine shrimp
TLDR
This study investigated the phylogenetic relationship and patterns of gene expression of sexual and asexual lineages of Eurasian Artemia brine shrimp, to assess how gene expression patterns are affected by the transition to asexuality.
Spatial Heterogeneity and the Evolution of Sex in Diploids
TLDR
It is found that inbreeding affects the evolution of sex through segregation, not recombination, and the model allows for a direct comparison of the forces acting on these related but different processes, illuminating the role of segregation.
Elimination of altered karyotypes by sexual reproduction preserves species identity.
TLDR
The reinterpretation of data from the literature strongly supports the hypothesis that the principal consequence of sexual reproduction is the reduction of drastic genetic diversity at the genome or chromosome level, resulting in the preservation of species identity rather than the provision of evolutionary diversity for future environmental challenges.

Recessive mutations and the maintenance of sex in structured populations.
TLDR
It is shown that low levels of population structure or inbreeding can greatly enhance the importance of recessive deleterious mutations in the context of sexual vs. asexual populations.
Sex releases the speed limit on evolution
TLDR
It is shown that sex can increase the rate of adaptation in the facultatively sexual single-celled chlorophyte Chlamydomonas reinhardtii, but that the benefits of sex depend crucially on the size of the population that is adapting: sex has a marked effect in large populations but little effect in small populations.
Species Interactions and the Evolution of Sex
TLDR
A population genetics model is developed that circumscribes a broad array of ecological and genetic interactions among species and derives the first general analytical conditions for the impact of species interactions on the evolution of sex.
Evidence from a New Zealand snail for the maintenance of sex by parasitism
TLDR
Male frequency in Potamopyrgus antipodarum, a dioecious freshwater snail with both sexual and parthenogenetic populations, is examined, finding the results do not-support the view that sex is maintained by a variable physical environment, but they are consistent with the idea thatsex is favoured by selection resulting from host–parasite interactions.
Sex increases the efficacy of natural selection in experimental yeast populations
TLDR
It is shown that, as predicted by the theory, sex increases the rate of adaptation to a new harsh environment but has no measurable effect on fitness in a new benign environment where there is little selection.
Test of synergistic interactions among deleterious mutations in bacteria
TLDR
The mutational deterministic hypothesis for the evolution of sex is not supported, because several pairs exhibit significant interactions for fitness, but they are antagonistic as often as they are synergistic.

TLDR
The purpose of this paper is to determine the conditions when this advantage of sexuality will outway three disadvantages of sexuality: the costs of males, of segregation, and of the additive component of recombination.
Drift Increases the Advantage of Sex in RNA Bacteriophage Φ6
TLDR
The effects of drift on existing genetic variation are revealed by minimizing the influence of variation on beneficial mutation rate by conducting an experiment in populations of RNA bacteriophage Φ6 initiated from a common source population at varying bottleneck sizes.
Parasitism, mutation accumulation and the maintenance of sex
TLDR
Results from computer simulations in which sexual populations were challenged by asexual lineages in the presence of coevolving parasites are presented.
Similarity Selection and the Evolution of Sex: Revisiting the Red Queen
TLDR
A population genetic model is presented here that includes both genotypic and similarity selection, allowing them to be directly compared in the same framework and showing that weakly virulent parasites are more likely to favor sex than are highly virulent ones.
