Abstract The reasons that sex and recombination are so widespread remain elusive. One popular hypothesis is that sex and recombination promote adaptation to a changing environment. The strongest evidence that increased recombination may evolve because recombination promotes adaptation comes from artificially selected populations. Recombination rates have been found to increase as a correlated response to selection on traits unrelated to recombination in several artificial selection experiments… Expand
Interference among deleterious mutations favours sex and recombination in finite populations
TLDR
This work shows that background selection against deleterious mutant alleles provides a stochastic advantage to sex and recombination that increases with population size, and offers a robust and broadly applicable explanation for the evolutionary advantage of recombination. Expand
Selective interference among deleterious mutations favours sex and recombination in finite populations regardless of the nature of epistasis
2 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 inExpand
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
Sex initiates adaptive evolution by recombination between beneficial loci
TLDR
This study found that the first mechanism dominated the initial phase of adaptive evolution in Brachionus calyciflorus rotifers during a natural selection experiment, and provided evidence for the hypothesis that sex can speed up adaptation by recombination between beneficial alleles of different loci, in particular during early stages of adaptive evolve in this system.

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.

Fitness-Dependent Recombination Can Be Evolutionarily Advantageous in Diploids: a Deterministic Mutation–Selection–Balance Model
TLDR
It is shown here that FD recombination can be evolutionarily advantageous in diploids subjected to purifying selection, and this advantage is associated with benefits from the differential rate of disruption of lower- vs higher-fitness genotypes, that can be manifested in systems with at least three selected loci. Expand
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. Expand
Recombination can evolve in large finite populations given selection on sufficient loci.
TLDR
It is shown that as selection acts on the authors' finite population, recombination increases the variance in expected log fitness, causing indirect selection on a recombination-modifying locus, enhancing the advantage of recombination in those populations with more loci. Expand
Strong artificial selection in domestic mammals did not result in an increased recombination rate.
TLDR
The data indicate that strong directional selection did not result in changes in recombination in domestic mammals, and that both upper and lower bounds for crossover rates may be tightly regulated. Expand
Natural selection promotes the evolution of recombination 2: during the process of natural selection*
TLDR
It is shown that natural selection acting on standing heritable variation always creates conditions favoring the evolution of recombination, in expectation, and that sex and recombination may have evolved more as a byproduct than as a catalyst of natural selection. Expand

Recombination load associated with selection for increased recombination.
TLDR
It is shown that a recombination load is to be expected even if selection favours increased genetic recombination, because of the fact that, although a modifier may suffer an immediate loss of fitness, it eventually becomes associated with a higher additive genetic variance in fitness, which allows a faster response to direction selection. Expand
The evolution of recombination: removing the limits to natural selection.
TLDR
It is concluded that selection for recombination will be substantial only if there is tight linkage within the genome or if many loci are subject to directional selection as during periods of rapid evolutionary change. Expand
The evolution of recombination in a heterogeneous environment.
TLDR
This article examines the joint effects of spatial heterogeneity in selection and epistasis on the evolution of recombination in a model with two patches and finds that including spatial heterogeneity extends the range of epistasis over which recombination can be favored. Expand
Increased recombination frequencies resulting from directional selection for geotaxis in Drosophila
TLDR
It is shown that long-term selection for positive or negative geotaxis in Drosophila melanogaster results in a dramatic increase in recombination rates in different genomic regions, allowing one to conclude that selection for fitness traits may be a powerful factor causing rather rapid changes in the recombination system.

TLDR
A general representation of multilocus selection is extended to allow recombination to depend on genotype, and demonstrates a general relation between selection on recombination and observable components of fitness variation, which is open to experimental test. Expand

TLDR
Although Weismann's hypothesis must be considered the leading candidate for the function of sex and recombination, nevertheless, many additional principles are needed to fully account for their evolution. Expand
The evolution of sex and recombination in a varying environment.
TLDR
Theoretical models of the evolutionary advantages of sex and genetic recombination in a temporally varying environment are analyzed and it is shown that the case of a steadily moving optimum is more favorable than a random optimum for the evolution of increased recombination. Expand
Genetic recombination and directional selection for DDT resistance in Drosophila melanogaster
TLDR
It is demonstrated in Drosophila that the response of a polygenic character (DDT resistance) to directional selection is sufficiently correlated with the genetic variability generated by recombination to bring about a corresponding increase in recombination rate. 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
