Sex and recombination are widespread, but explaining these phenomena has been one of the most difficult problems in evolutionary biology. Recombination is advantageous when different individuals in a population carry different advantageous alleles. By bringing together advantageous alleles onto the same chromosome, recombination speeds up the process of adaptation and opposes the fixation of harmful mutations by means of Muller's ratchet. Nevertheless, adaptive substitutions favour sex and… Expand
Deleterious Mutations and Selection for Sex in Finite Diploid Populations
TLDR
Analytical two- and three-locus models are developed to study the effect of recurrent deleterious mutations on a modifier gene increasing sex, in a finite diploid population and show that excess of heterozygosity generated by finite population size is an important component of selection for sex. Expand
Influences of Dominance and Evolution of Sex in Finite Diploid Populations
TLDR
An infinite loci model is adopted and shows that with different levels of dominance, segregation and recombination may play different roles, and illustrates that the existence of dominance is an important mechanism that affects the evolution of sex. Expand
Evolution of sex and recombination in large, finite populations
TLDR
Computer simulations are used to investigate the evolution of a recombination modifier under three different scenarios of recurrent mutation in a finite population and observe that adding even a small number of advantageous mutations increases the fixation rate of modifiers that increase recombination, especially if the effects of deleterious mutations are weak.

TLDR
It is plausible that spatial and temporal fluctuations in selection generate much more fitness variance, and hence selection for recombination, than can be explained by uniformly deleterious mutations or species-wide selective sweeps. Expand
Relative effects of segregation and recombination on the evolution of sex in finite diploid populations
TLDR
It was observed that the twofold cost of sex was easily to overcome in diploids if a sex modifier caused a moderate frequency of sex, and the combined effects of segregation and recombination strongly contributed to the evolution of sex in diPloids. Expand
Sex and Deleterious Mutations
TLDR
The quantification of the range of selective effects that favors recombination leads to suggest that, if in stressful environments the effect of deleterious mutations is enhanced, a connection between sex and stress could be expected, as it is found in several species. Expand
Sex and recombination purge the genome of deleterious alleles: An Individual Based Modeling Approach
TLDR
The purifying selection hypothesis, the hypothesis that recombination due to sexual reproduction helps to eliminate deleterious alleles from the genome through the selection of reduced function mutations, is corroborated. Expand
Genetic Load in Sexual and Asexual Diploids: Segregation, Dominance and Genetic Drift
TLDR
Overall, the mutation load that arises through the absence of segregation in asexuals may greatly exceed previous predictions that ignored genetic drift. Expand
Selection for sex in finite populations

TLDR
Extrapolating the results from three‐locus models to a large number of loci at mutation–selection balance indicates that in the parameter range where indirect selection is strong enough to outweigh a substantial cost of sex, interactions between selected loci have a stronger effect than the sum of individual effects of each selected locus.

Recombination Speeds Adaptation by Reducing Competition between Beneficial Mutations in Populations of Escherichia coli
TLDR
Using the F plasmid to mediate recombination in the bacterium Escherichia coli and measuring its effect on adaptation at high and low mutation rates provides experimental support for the Fisher–Muller model and demonstrates that plasmids-mediated gene transfer can accelerate bacterial adaptation.

TLDR
To the surprise, it is found that drift accounted for the majority of selection for increased recombination observed in simulations of small to moderately large populations, suggesting that, unless selected populations are large, epistasis plays a secondary role in the evolution of recombination.

TLDR
The results show that, in a small population, increased recombination can be selected, even in the absence of epistasis or beneficial mutations, and a higher deleterious mutation rate is required for an increase in recombination rate to be favored in haploid populations. Expand
Evolution of genetic variability and the advantage of sex and recombination in changing environments.
TLDR
It is shown by Monte Carlo simulations that if the directional-selection component prevails, then freely recombining populations gain a substantial evolutionary advantage over nonrecombining and asexual populations that goes far beyond that recognized in previous studies. Expand
Mutation-selection balance and the evolutionary advantage of sex and recombination.
TLDR
It is shown that equilibrium mean fitness is least for asexual populations, and synergistic epistasis on the scale of log fitness, such that log fitness declines more steeply as n increases, means fitness behaves in the opposite way. Expand
The evolutionary advantage of recombination.
TLDR
Computer simulations of substitution of favorable mutants and of the long-term increase of deleterious mutants verified the essential correctness of the original Fisher-Muller argument and the reality of the Muller ratchet mechanism. Expand

Based on the FISHER-MULLER theory of the evolution of recombination, an argument can be constructed predicting that a recessive allele favoring recombination will be favored, if there are eitherExpand
Evolution of Recombination Due to Random Drift
TLDR
The method developed within this article allows us to quantify the strength of selection acting on a modifier allele that increases recombination in a finite population and indicates that stochastically generated linkage disequilibrium do select for increased recombination, a result that is confirmed by Monte Carlo simulations.

Some evolutionary consequences of deleterious mutations
Most mutations with observable phenotypic effects are deleterious. Studies of Drosophila and inbred plant populations suggest that a new individual may have a mean number of new deleterious mutationsExpand
Selection for Recombination in Structured Populations
TLDR
It is demonstrated that substantial levels of linkage disequilibria can accumulate by drift in the presence of selection in populations of any size, provided that the population is subdivided, and that the stochastic theories of the evolution of sex apply to a much broader range of conditions than previously expected.

Deleterious mutations as an evolutionary factor. 1. The advantage of recombination.
TLDR
A population with u deleterious mutations per genome per generation is considered in which only those individuals that carry less than a critical number of k mutations are viable and selection at a locus that determines recombination frequency of the whole genome is considered. Expand
