Fisher's mechanism of sexual selection is a fundamental element of evolutionary theory. In it nonrandom mate choice causes a genetic covariance between a male trait and female preference for that trait and thereby generates a positive feedback process sustaining accelerated coevolution of the trait and preference. Numerous theoretical models of Fisher's mechanism have confirmed its mathematical underpinnings, yet biologists have often failed to find evidence for trait‐preference genetic… Expand

The causes of variation in the presence of genetic covariance between sexual traits and preferences
TLDR
Trait–preference genetic covariance appears to be widespread and therefore represents an important and currently underappreciated factor in the coevolution of traits and preferences. Expand
The problem of measuring trait-preference correlations without disrupting them
A key element at the heart of the Fisher–Lande–Kirkpatrick model of the sexual selection process is the genetic correlation between (male) trait and (female) preference. The strength of this… Expand
Mechanisms of Assortative Mating in Speciation with Gene Flow: Connecting Theory and Empirical Research
TLDR
By providing a clear framework for mating rules and how these rules affect speciation through maintaining or eroding barriers to gene flow among closely related species or populations, this work hopes to inspire greater alignment in the ways that both theoreticians and empiricists study mating rules. Expand
Genetic variation in male attractiveness: It is time to see the forest for the trees
TLDR
It is shown how relying on individual male traits, instead of overall attractiveness, can produce biased estimates of Fisherian benefits of female choice, which can be substantial, especially when many traits contribute to male attractiveness. Expand
Mate‐choice copying: A fitness‐enhancing behavior that evolves by indirect selection
A spatially explicit, individual‐based simulation model is used to study the spread of an allele for mate‐choice copying (MCC) through horizontal cultural transmission when female innate preferences… Expand
The relation between R. A. Fisher's sexy‐son hypothesis and W. D. Hamilton's greenbeard effect
Recent years have seen a growing interest in the overlap between the theories of kin selection and sexual selection. One potential overlap is with regards to whether R. A. Fisher's “sexy‐son”… Expand
Variation in signal–preference genetic correlations in Enchenopa treehoppers (Hemiptera: Membracidae)
TLDR
It is argued that some forms of weak signal–preference genetic correlation may have important evolutionary consequences and be stronger in the species that showed greater amounts of genetic variation in signals and preferences. Expand
Fisher's sons’ effect in sexual selection: absent, intermittent or just low experimental power?
TLDR
It is shown here that systematic failure of studies to reject the null hypothesis that rG = 0 is almost certainly due to the low power of most experimental designs used and that current data make it difficult to definitively test a key component of the Fisher effect. Expand
Genetic coupling of signal and preference facilitates sexual isolation during rapid speciation
TLDR
This work estimated the location of QTL underlying interspecific variation in both female preference and male pulse rate from the same mapping populations, pointing to a major role for genetic coupling in the quantitative evolution of a reproductive barrier and rapid speciation in Laupala. Expand
Genetic coupling of signal and preference facilitates sexual isolation during rapid speciation

META‐ANALYSIS SUGGESTS CHOOSY FEMALES GET SEXY SONS MORE THAN “GOOD GENES”
TLDR
The results support “Fisherian” models of preference evolution, while providing equivocal evidence for “good genes,” and pinpoint research directions that should stimulate progress in the understanding of the evolution of female choice. Expand
The evolution of phenotypes and genetic parameters under preferential mating
TLDR
It is concluded that rapid coevolution of preferences and preferred traits is unlikely in natural populations, but that the parameter combinations most conducive to it are most likely to occur in lekking species. Expand
THE STUDY OF INTERSEXUAL SELECTION USING QUANTITATIVE GENETICS
TLDR
The general conclusion is that sexual traits and mating preferences show large genetic variation and are genetically correlated. Expand
SEXUAL SELECTION AND THE EVOLUTION OF FEMALE CHOICE
  • M. Kirkpatrick
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 1982
TLDR
The primary conclusion of the present paper is that the initial selective advantages for the female preference assumed by Fisher, O'Donald, and many later authors are not necessary for either the origin or subsequent elaboration of mating preferences for traits associated with reduced survivorship. Expand
Genetic Analysis of Female Preference Functions as Function‐Valued Traits
TLDR
This article takes an alternative approach, treating female preference as a function‐valued trait and exploiting random‐coefficient models to characterize the genetic basis of female preference without measuring preference functions in each individual, and applies this approach to Drosophila bunnanda. Expand
RUNAWAY SEXUAL SELECTION WITHOUT GENETIC CORRELATIONS: SOCIAL ENVIRONMENTS AND FLEXIBLE MATE CHOICE INITIATE AND ENHANCE THE FISHER PROCESS
TLDR
Allowing feedback from the social environment resolves discrepancies between theoretical predictions and empirical data, such as why indirect selection on female preferences, theoretically weak, might be sufficient for preferences to become elaborated. Expand
Testing the genetics underlying the co-evolution of mate choice and ornament in the wild
TLDR
Insight is provided into the field of sexual selection by showing that genes coding for mate choice for an ornament probably evolve by their own pathways instead of ‘hitchhiking’ with genes coded for the ornament. Expand
The genetic basis of female mate preferences
TLDR
The evidence for genetic variation in female and male mate preferences is reviewed, and evidence for the presence of genetic covariance between mate preferences and sexual traits in the other sex is reviewed. Expand
Test of indirect models of selection in the Trinidad guppy
TLDR
In a direct test of indirect selection models, mass selection on attractive male coloration did not result in a correlated response in female preference in replicate treatments from a high predation population of the Trinidad guppy. Expand
SEXUAL SELECTION AND THE EVOLUTION OF COSTLY FEMALE PREFERENCES: SPATIAL EFFECTS
  • T. Day
  • Biology, Medicine
  • Evolution; international journal of organic evolution
  • 2000
TLDR
A model of Fisher's runaway process is presented to demonstrate that costly female preference evolves very easily when space is explicitly included in the model, and shows that abrupt changes in the optimal male phenotype across space can result in an amplification of this pattern when preference has a small cost.
