“…To set the variance, we extracted data from the literature on the relative phenotypic variance of preference to the preferred trait. The ratios for the four species for which such data are available (Gryllus texensis, Achroia grisella, Colias eurythem and Ficedula albicollis) were 1.2, 1.63, 0.8 and 1.0, respectively (sources: Gray and Cade, 1999;Zhou et al, 2011;Sappington and Taylor, 1990;Qvarnström et al, 2006). Thus for these four species the phenotypic variance in preference is similar to the variance in the preferred trait.…”

“…The third preference function examined in the present paper assumes that there are two types of males and that females have a preference for one or the other. This difference may be naturally occurring, as in the two color morphs of the sulfur butterfly, Colias eurytheme (Sappington and Taylor, 1990), though in this case mate selection appears to be based on the different pheromones of the two morphs (but see Papke et al, 2007 for evidence on UV reflectance). A similar situation is found in the wing dimorphic sand cricket, Gryllus firmus, in which females, by their preference for males that sing the most, preferentially favor micropterous males over macropterous males (Crnokrak and Roff, 1995).…”

The evolution of mate choice is a function of the heritability of preference. Estimation in the laboratory is typically made by presenting a female with a limited number of males. We show that such an approach produces a downwardly biased estimate, which we term the heritability of choice. When preference is treated as a threshold trait then less biased estimates are obtained particularly for preferences based on the relative value of the preferred trait. Because females in the wild typically survey on average less than five males we argue that the heritability of choice may be more meaningful than the heritability of preference. The restricted number of males surveyed can lead to a reduction in the phenotypic variance of the preferred trait in the group of males selected by the females if the phenotypic variance in preference is equal to or less than the phenotypic variance in the referred trait. If the phenotypic variance in preference exceeds that of the preferred trait then the opposite occurs. A second effect of the restricted number of males sampled is that females are likely to mate initially with males that are not the most preferred. The failure to find the most preferred male may account for the common observation of multiple matings and extra-pair copulations. We suggest that current explanations for polyandry need to take this failure into account.

“…These limitations appear to be reflected in the literature. Few convincing examples of disruptive sexual selection have been described within populations (Gross 1985;Sappington and Taylor 1990;Greene et al 2000). While sexual selection in these cases certainly contributes to variability in courtship signals, no robust intraspecific examples have yet been described of the sorts of strong, disruptive mating preferences required to tear apart even largely symmetrical populations.…”

Sympatric Speciation by Sexual Selection Alone Is Unlikely

Abstract. According to Darwin, sympatric speciation is driven by disruptive, frequency-dependent natural selection caused by competition for diverse resources. Recently, several authors have argued that disruptive sexual selection can also cause sympatric speciation. Here, we use hypergeometric phenotypic and individual-based genotypic models to explore sympatric speciation by sexual selection under a broad range of conditions. If variabilities of preference and display traits are each caused by more than one or two polymorphic loci, sympatric speciation requires rather strong sexual selection when females exert preferences for extreme male phenotypes. Under this kind of mate choice, speciation can occur only if initial distributions of preference and display are close to symmetric. Otherwise, the population rapidly loses variability. Thus, unless allele replacements at very few loci are enough for reproductive isolation, female preferences for extreme male displays are unlikely to drive sympatric speciation. By contrast, similarity-based female preferences that do not cause sexual selection are less destabilizing to the maintenance of genetic variability and may result in sympatric speciation across a broader range of initial conditions. Certain groups of African cichlids have served as the exclusive motivation for the hypothesis of sympatric speciation by sexual selection. Mate choice in these fishes appears to be driven by female preferences for extreme male phenotypes rather than similaritybased preferences, and the evolution of premating reproductive isolation commonly involves at least several genes. Therefore, differences in female preferences and male display in cichlids and other species of sympatric origin are more likely to have evolved as isolating mechanisms under disruptive natural selection.

“…Yet, surprisingly few empirical tests of this assumption can be found in the literature. The observed high variability in pheromone composition of male Colias butterflies has been hypothesized to be due to disruptive sexual selection exerted by females of different colour morphs within populations (Sappington & Taylor 1990). In guppies and sideblotched lizards, within-population polymorphism in male sexual ornamentation may be promoted and maintained by disruptive female mating preferences on complex fitness surfaces with multiple peaks for male traits (Blows et al 2003;Bleay & Sinervo 2007).…”

Theory suggests that genetic polymorphisms in female mating preferences may cause disruptive selection on male traits, facilitating phenotypic differentiation despite gene flow, as in reinforcement or other models of speciation with gene flow. Very little experimental data have been published to test the assumptions regarding the genetics of mate choice that such theory relies on. We generated a population segregating for female mating preferences and male colour dissociated from other species differences by breeding hybrids between species of the cichlid fish genus Pundamilia. We measured male mating success as a function of male colour. First, we demonstrate that non-hybrid females of both species use male nuptial coloration for choosing mates, but with inversed preferences. Second, we show that variation in female mating preferences in an F 2 hybrid population generates a quadratic fitness function for male coloration suggestive of disruptive selection: intermediate males obtained fewer matings than males at either extreme of the colour range. If the genetics of female mate choice in Pundamilia are representative for those in other species of Lake Victoria cichlid fish, it may help explain the origin and maintenance of phenotypic diversity despite some gene flow.
