Quantitative genetic models for the evolution of exaggerated male traits through female mate choice predict that selection on male ornaments should cause a correlated response in female preferences. Furthermore, female selectivity should be inversely related to costs of mate choice. Here we use a stalkeyed fly Cyrtodiopsis dalmanni (Diptera:Diopsidae), which exhibits pronounced sexual dimorphism in eye span, to evaluate these predictions. Field observations reveal that each evening females…

Sex-linked Correlated Responses in Female Reproductive Traits to Selection on Male Eye Span in Stalk-eyed Flies1

The absence of any change in sperm length or testis size between lines indicates that changes in female traits are unlikely due to correlated selection mediated by sperm competition, and the presence of nonadditive allelic effects on genetically correlated female traits combined with additive alleliceffects on a male ornament provides a previously unrecognized mechanism by which genetic variation could be maintained despite strong sexual selection.

Male eye span in stalk-eyed flies indicates genetic quality by meiotic drive suppression

It is shown that females prefer ornaments that indicate genetic quality generated by transmission conflict between the sex chromosomes, and male eye span signals genetic quality by influencing the reproductive value of offspring.

Evolution of female mating preferences in stalk-eyed flies

It is concluded that female sensory bias for males with long eye span did not exist in a common ancestor to these species, and female preference and remating propensity either coevolved with eye span dimorphism or evolved after male eye stalks elongated.

Male mate preference for female eyespan and fecundity in the stalk-eyed fly, Teleopsis dalmanni

Results show that male mate preferences are a prevalent feature of a canonical example of female mate choice sexual selection and that males use multiple cues when they assess females as potential mates.

Direct and correlated responses to artificial selection on male mating frequency in the stalk‐eyed fly Cyrtodiopsis dalmanni

The results suggest that costs associated with the production and maintenance of large accessory glands, although yet to be identified, are likely to be a major constraint on mating frequency in natural populations of C. dalmanni.

Female mate choice and male ornamentation in the stalk-eyed fly, diasemopsis meigenii

It is shown that choosiness and selection, but not the preference function, are elevated in mated females, and evidence is found for the heightened condition dependence of the male sexual trait (male eyespan), and for a novel gene-by-environment interaction.

Effects of multiple mating and male eye span on female reproductive output in the stalk-eyed fly, Cyrtodiopsis dalmanni

Examination of the effects of multiple mating and male eye span on short-term reproductive output in the stalk-eyed fly suggested that obtaining a sufficient sperm supply is an important benefit associated with multiple mating.

Condition-dependent signalling of genetic variation in stalk-eyed flies

It is shown that genetic variation underlies the response to environmental stress of a sexual ornament (male eye span) in the stalk-eyed fly Cyrtodiopsis dalmanni, and this results strongly support the hypothesis that female mate choice yields genetic benefits for offspring.

Male sexual ornament size is positively associated with reproductive morphology and enhanced fertility in the stalk-eyed fly Teleopsis dalmanni

Male eyespan in stalk-eyed flies is subject to strong directional mate preference and is a reliable indicator of male reproductive quality – both because males with larger eyespan have bigger accessory glands and testes, and also as they confer higher fertility on females.

No detectable genetic correlation between male and female mating frequency in the stalk-eyed fly Cyrtodiopsis dalmanni

This study suggests that the genes which influence remating may not be the same in the sexes, and that females remate frequently in this species to gain as yet unidentified benefits.



Artificial sexual selection alters allometry in the stalk-eyed fly Cyrtodiopsis dalmanni (Diptera: Diopsidae)

The results suggest that the exaggerated eye span of male C. dalmanni is maintained by natural selection opposing sexual selection rather than by lack of or asymmetry in additive genetic variation.

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.

Female sticklebacks use male coloration in mate choice and hence avoid parasitized males

It is shown that in the three-spined stickleback (Gasterosteus aculeatus) the intensity of male red breeding coloration positively correlates with physical condition, and the females recognize the formerly parasitized males by the lower intensity of theirbreeding coloration.

Positive genetic correlation between female preference and preferred male ornament in sticklebacks

This prediction is tested at the within-population level with three-spined sticklebacks, Gasterosteus aculeatus, which show conspicuous sexual dichromatisnr, and the redness of the sons correlated with the preference for red of their sisters, thus the two traits show positive genetic correlation.

The models elucidate genetic mechanisms that can initiate or contribute to rapid speciation by sexual isolation and divergence of secondary sexual characters in polygamous species.

Selection of exaggerated male traits by female aesthetic senses

It is reported that mechanisms concerned with signal recognition possess inevitable biases in response that act as important agents of selection on signal form, and the existence of such biases may be sufficient to explain the evolution of exaggerated male secondary sexual traits, and elaborate signals in general.

Non-random mating in Adalia bipunctata (the two-spot ladybird). III. New evidence of genetic preference

The ladybirds used in the repeat experiment were collected from a wild population in which melanic frequencies had dropped from 35 to 10 per cent in 3 years, and the overall mating rate was twice that of the original experiment.


This analysis shows that evolutionary stable exaggeration of female preference can be achieved if mutation pressure on the male character is biased, that is, mutation has a directional effect at this equilibrium female fitness is not maximized.

The evolution of mating preferences and the paradox of the lek

There is growing support for direct selection, in which preferences evolve because of their direct effects on female fitness rather than the genetic effects on offspring resulting from mate choice.
