The tendency of organisms to reproduce by cross-fertilization despite numerous disadvantages relative to self-fertilization is one of the oldest puzzles in evolutionary biology. For many species, the primary obstacle to the evolution of outcrossing is the cost of production of males, individuals that do not directly contribute offspring and thus diminish the long-term reproductive output of a lineage. Self-fertilizing (‘selfing’) organisms do not incur the cost of males and therefore should… Expand
Partial selfing eliminates inbreeding depression while maintaining genetic diversity
TLDR
Analysis of genome-wide single-nucleotide polymorphism during experimental evolution and after enforced inbreeding suggests that, under partial selfing, populations were purged of un linked deleterious recessive alleles that segregate in the ancestral population, which in turn allowed the expression of unlinked overdominant fitness loci.

The role of hermaphrodites in the experimental evolution of increased outcrossing rates in Caenorhabditis elegans
TLDR
Using experimental evolution in six populations with initially low standing levels of genetic diversity, it is shown that population-wide fitness improved during 100 generations, and that outcrossing is adaptive, indicating that outCrossing facilitates adaptation to novel environments. Expand

TLDR
An overview of existing research on the evolutionary basis behind different reproductive modes is provided, with a focus on explaining the population genetic effects favouring low outcrossing rates in either partially selfing or asexual species. Expand
Evolutionary consequences of self-fertilization in plants
TLDR
It is concluded that while some aspects of the hypothesis of selfing as a dead end are supported by theory and empirical results, the evolutionary and ecological mechanisms remain unclear. Expand
Reproductive assurance drives transitions to self-fertilization in experimental Caenorhabditis elegans
TLDR
Results show that self-compatible hermaphrodites provide reproductive assurance to a male-female population facing a novel environment where outcrossing is limiting, and suggest that the success of transitions to selfing hinges on adaptation of obligate outcrossed populations to the environment whereOutcrossing was once a limiting factor. Expand
Current hypotheses for the evolution of sex and recombination.
TLDR
Current theoretical and experimental evidence seems to favor the hypothesis that sex breaks down selection interference between new mutants, or it acts as a mechanism to shuffle genotypes in order to repel parasitic invasion, however, there is still a need to collect more data from natural populations and experimental studies, which can be used to test different hypotheses.

Purging Deleterious Mutations under Self Fertilization: Paradoxical Recovery in Fitness with Increasing Mutation Rate in Caenorhabditis elegans
Background The accumulation of deleterious mutations can drastically reduce population mean fitness. Self-fertilization is thought to be an effective means of purging deleterious mutations. However,Expand
Fitness effects of thermal stress differ between outcrossing and selfing populations in Caenorhabditis elegans
TLDR
It is found that thermal stress affects fitness of outcrossers much more drastically than that of selfers, showing that apart from the potential for recombination, the selective pressures imposed by the same environmental change can differ between populations expressing different reproductive systems and affect their adaptive potential.

Evolution of Outcrossing in Experimental Populations of Caenorhabditis elegans
TLDR
Results suggest that androdioecious males are maintained at intermediate frequencies because outcrossing is adaptive. Expand

TLDR
The results support the hypothesis that extinction by mutational meltdown is why selfing hermaphroditic taxa are rare, despite their frequent appearance over evolutionary time. Expand

Selection against males in Caenorhabditis elegans under two mutational treatments
TLDR
It is found that experimentally increasing the mutational load in four different isogenic wild isolates using 10 generations of Ethylmethane sulphonate (EMS) and UV irradiation mutagenesis significantly diminishes the cost of males. Expand
THE EVOLUTION OF SELF‐FERTILIZATION AND INBREEDING DEPRESSION IN PLANTS. I. GENETIC MODELS

TLDR
Genetic models are constructed which allow inbreeding depression to change with the mean selfing rate in a population by incorporating both mutation to recessive and partially dominant lethal and sublethal alleles at many loci and mutation in quantitative characters under stabilizing selection.

TLDR
Experimental evidence is provided consistent with deleterious mutational explanations for the evolution of sex in principle, but the action of other processes is required to explain the evolutionof sex in entirety. Expand
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. Expand
Mutation Accumulation in Populations of Varying Size: The Distribution of Mutational Effects for Fitness Correlates in Caenorhabditis elegans
TLDR
It is shown that the mean fitness decline experienced by larger populations is actually greater than expected on the basis of the estimates of mutational parameters, which could be consistent with the existence of a common class of mutations with small individual effects. Expand
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.

The extent of genetic variation for characters directly related to outcrossing, such as male frequency, male mating ability, and male reproductive success, in several wild isolates of the nematode Caenorhabditis elegans is determined. Expand
