The "sexy-sperm" hypothesis proposes that multiple-mating females have a selective advantage over single-mating females because the former are fertilized by the most competitive sperm and have sons that produce competitive sperm. A deterministic genetical model of the sexy-sperm process is described here. It assumes one locus that influences sperm competitive ability and a second locus that influences female mating behavior. The conditions for sperm competition to promote the evolution of… 

Multiple mating, sperm competition and meiotic drive

TLDR
Competition within ejaculates may be one reason why females choose to mate with multiple males, and selection will favor female mating behavior that reduces the distorter's equilibrium frequency.

A "Good-Sperm" Model Can Explain the Evolution of Costly Multiple Mating by Females

Multiple mating by females (or polyandry) is one of the most controversial subjects in sexual selection and mating systems theory (Smith 1984; Halliday and Arnold 1987; Birkhead and Moller 1992). In

Quantitative genetic correlation between trait and preference supports a sexually selected sperm process

TLDR
The data provided provide quantitative genetic support for the role of a sexually selected sperm process in the evolutionary divergence of sperm morphology, in much the same manner as precopulatory female preferences drive the evolutionary separation of male secondary sexual traits.

Sexual selection and the evolution of sperm quality.

TLDR
It is argued that information about sperm evolution gained from non-human animals has enormous potential to further the understanding of the factors that impact human fertility.

The evolution of polyandry: multiple mating and female fitness in insects

TLDR
A meta-analysis of 122 experimental studies addressing the direct effects of multiple mating on female fitness in insects shows that females gain directly from multiple matings in terms of increased lifetime offspring production, and supports the existence of an intermediate optimal female mating rate.

The genetic basis of traits regulating sperm competition and polyandry: can selection favour the evolution of good- and sexy-sperm?

TLDR
The emerging pattern of sex linkage in genes for polyandry is more consistent with an evolutionary history of antagonistic selection over mating frequency and is advocated for further development of GS-SS theory to take account of the complex evolutionary dynamics imposed by sexual conflict over mating Frequency.

Female remating, sperm competition and sexual selection in Drosophila.

TLDR
This work examined female remating with respect to sperm competition and sexual selection in Drosophila and addressed the possible benefits for females, and reviewed the role of accessory gland fluid in remating.

Genetic quality and sexual selection: an integrated framework for good genes and compatible genes

TLDR
This paper presents a verbal model of the effect of good genes sexual selection and compatible genesSexual selection on population genetic variation in fitness, and discusses the potential trade‐offs that might exist betweenmate choice for good genes and mate choice for compatible genes.

Explaining the evolution and maintenance of polyandry remains a key challenge in evolutionary ecology. One appealing explanation is the sexually selected sperm (SSS) hypothesis, which proposes that

A Diploid "Sexy Son" Model

TLDR
A diploid sexy-son model is presented, demonstrating by counterexample that generalizations from haploid and additive polygenic models are not valid and the maximization principles derived from other models can be violated in the diploids case.

Evolution of Female Choice and Male Parental Investment in Polygynous Species: The Demise of the "Sexy Son"

TLDR
These models address the "sexy son" hypothesis of Weatherhead and Robertson (1979), which contends that selection can create an equilibrium at which females on the average mate with certain attractive types of males that give them inferior material resources and therefore decrease the females' immediate reproductive success.

The population genetics of sperm displacement.

TLDR
The experimental work involved the use of three genetic marker stocks in double and triple matings and indicated stable equilibria if (1) there is heterosis, and (2) there are certain nontransitive relationships in displacing ability among the different kinds of double matings.
