TLDR
The completely deterministic model is treated, that is, an effectively infinite population so that chromosome frequencies suffice to describe the population and it is shown that if the mutations are favorable and the double mutant is fitter than expected under simple multiplicity, then the frequency of the double is the same with recombination as without it.About:

The evolutionary advantage of recombination
TL;DR: 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.

Why Sex and Recombination
TL;DR: 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.

Resolving the paradox of sex and recombination.
Sarah P. Otto,Thomas Lenormand +1 more
TL;DR: This article showed that a large body of theoretical work has shown that sexual reproduction and recombination should only evolve under a restricted set of conditions, and that this discrepancy might result from the fact that previous models have ignored important complexities that face natural populations, such as genetic drift and the spatial structure of populations.

Classification of Hypotheses on the Advantage of Amphimixis
TL;DR: A classification of hypotheses on the advantage of amphimixis over apomixis is presented, and two of them seem most plausible: better responsiveness of the amphimictic population to widely fluctuating selection, and lower mutation load in the amphimsic population under synergistic selection against deleterious mutations.

The Genetical Theory of Natural Selection
TL;DR: Although it is true that most text-books of genetics open with a chapter on biometry, closer inspection will reveal that this has little connexion with the body of the work, and that more often than not it is merely belated homage to a once fashionable study.
Journal ArticleDOI
Some Genetic Aspects of Sex
TL;DR: There is no basic biological reason why reproduction, variation and evolution can not go indefinitely without sexuality or sex; therefore, sex is not, in an absolute sense, a necessity, it is a "luxury."

Evolution in Sexual and Asexual Populations
James F. Crow,Motoo Kimura +1 more
TL;DR: The evolution of diploidy from haploidy confers an immediate reduction in the mutation load by concealment of deleterious recessives, but this advantage is lost once a new equilibrium is reached and the development of diPloidy may be because of an immediate advantage rather than because of any permanent benefit.

Evolution in sexual and asexual populations
TL;DR: In a simple model case, the rates of evolution in an asexual and a sexual haploid population are compared and it is shown that, if the genetic variance of the population is generated by mutation in a uniform environment, sexual reproduction confers no advantage, but if it has arisen because selection has favored different genotypes in different environments, then sexual reproduction will accelerate adaptation to a new environment.
