Why sex evolved and persists is a problem for evolutionary biology, because sex disrupts favourable gene combinations and requires an expenditure of time and energy. Further, in organisms with unequal-sized gametes, the female transmits her genes at only half the rate of an asexual equivalent (the twofold cost of sex). Many modern theories that provide an explanation for the advantage of sex incorporate an idea originally proposed by Weismann more than 100 years ago: sex allows natural… 
Evolutionary biology: Why sex is good
TLDR
Experiments verify the idea that sex makes natural selection more effective by increasing genetic variation, and this was found to be the case in the ‘minimalist’ yeast in harsh environments.
Sex enhances adaptation by unlinking beneficial from detrimental mutations in experimental yeast populations
TLDR
Sex appeared to facilitate adaptation not just by more rapidly combining beneficial mutations, but also by unlinking beneficial from detrimental mutations: sex allowed selection to operate on both types of mutations more effectively compared to asexual populations.
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.
Molecular evolution: Sex accelerates adaptation
TLDR
Using the experimental evolution of Saccharomyces cerevisiae as a model system, Michael Desai and colleagues find that sexual reproduction increases fitness by reducing clonal interference between beneficial mutations and alters the type of mutations that are fixed by natural selection.
Sex Speeds Adaptation by Altering the Dynamics of Molecular Evolution
TLDR
It is demonstrated that sex both speeds adaptation and alters its molecular signature by allowing natural selection to more efficiently sort beneficial from deleterious mutations.
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.
Evolutionary genetic consequences of facultative sex and outcrossing
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.
The ecology of sexual reproduction
TLDR
The evidence from natural populations and from laboratory experiments point to antagonistic coevolution as a potent and possibly ubiquitous force of selection favouring cross‐fertilization and recombination.
Higher rates of sex evolve during adaptation to more complex environments
TLDR
It is shown that adaptation to different environments results in varying amounts of sex and, more importantly, that higher levels of sex evolve when adapting to more complex environments, which helps explain why so many natural populations maintain such high levels ofsex.

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 effect of sex on adaptation to high temperature in heterozygous and homozygous yeast
TLDR
It is found that there was an initial cost of sex for all the sexual strains, which was indicated by a sharp increase in the proportion of asexuals after the induction of sex.
Why sex and recombination?
TLDR
The effect of sex and recombination in breaking down negative correlations between favorable variants at different genetic loci, which increases the efficiency of natural selection, is likely to be a major factor favoring their evolution and maintenance.

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.
Estimates of the rate and distribution of fitness effects of spontaneous mutation in Saccharomyces cerevisiae.
TLDR
Like other recently tested model organisms, wild-type yeast have low mutation rates, with high mean fitness costs per mutation, and inactivation of mismatch repair increases the frequency of slightly deleterious mutations by approximately two orders of magnitude.
Some Genetic Aspects of Sex
FPROM the genetic point of view it is advantageous to begin by considering sex in the broader sense of sexuality. It is not generally realized that genetics has finally solved the age-old problem of
Significant competitive advantage conferred by meiosis and syngamy in the yeast Saccharomyces cerevisiae.

TLDR
Overall, sexual strains with heterozygous genetic backgrounds had a significantly higher initial relative competitive ability than those with homozygous backgrounds, suggesting the advantage of mating type heterozygosity in this organism extends far beyond the ability to recombine meiotically.
Sex slows down the accumulation of deleterious mutations in the homothallic fungus Aspergillus nidulans.
TLDR
It is shown that slightly deleterious mutations accumulate at a lower rate in the sexual pathway than in the asexual pathway, and it is proposed that this advantage results from intra-organismal selection of the fittest gametes or zygotes, which is more stringent in the costly sexual pathway.
Suitability of replacement markers for functional analysis studies inSaccharomyces cerevisiae
TLDR
It is demonstrated that HO is a selectively neutral site for gene replacement, but there is a significant marker effect associated with HIS3 which is dependent on the physiological conditions used for the competition experiments, and nutritional markers should not be used to generate deletion mutants for quantitative analysis of gene function in yeast.

TLDR
Results support the Weismann-Fisher-Muller hypothesis for the maintenance of sex in natural populations and suggest that directional selection used up the variation generated by meiotic recombination and thereby conferred a fitness advantage to the sexual lines.
