“…The original proposition that female promiscuity might evolve as a genetic corollary of selection on male promiscuity (8, 18) has been criticized for its assumption that the same physiological mechanisms would underlie mating behavior in each sex (19). In apparent support of this criticism, a range of studies have failed to find a positive genetic correlation between male and female mating speed or mating frequency in chicken (20), Drosophila (21), stalk-eyed flies (22), and bean beetles (23). Only one study on mating frequency in burying beetles (24) has found a strong between-sex genetic correlation, although mating frequency was measured here with the same partner rather than with different partners.…”

In many species that form socially monogamous pair bonds, a considerable proportion of the offspring is sired by extrapair males. This observation has remained a puzzle for evolutionary biologists: although mating outside the pair bond can obviously increase the offspring production of males, the benefits of such behavior to females are less clear, yet females are known to actively solicit extrapair copulations. For more than two decades adaptionist explanations have dominated the discussions, yet remain controversial, and genetic constraint arguments have been dismissed without much consideration. An intriguing but still untested hypothesis states that extrapair mating behavior by females may be affected by the same genetic variants (alleles) as extrapair mating behavior by males, such that the female behavior could evolve through indirect selection on the male behavior. Here we show that in the socially monogamous zebra finch, individual differences in extrapair mating behavior have a hereditary component. Intriguingly, this genetic basis is shared between the sexes, as shown by a strong genetic correlation between male and female measurements of extrapair mating behavior. Hence, positive selection on males to sire extrapair young will lead to increased extrapair mating by females as a correlated evolutionary response. This behavior leads to a fundamentally different view of female extrapair mating: it may exist even if females obtain no net benefit from it, simply because the corresponding alleles were positively selected in the male ancestors.

“…However, the evidence is inconsistent, as other selection experiments in D. melanogaster have failed to show significant correlated responses to selection for mating speed and/or frequency (Gromoko and Newport 1988; Veuille and Mazeau 1988; Sgro et al 1998). In other systems, such as domestic chickens, Gallus domesticus (Cheng and Siegel 1990), stalk‐eyed flies, Cyrtodiopsis dalmanni (Grant et al 2005), and bean beetles, Callosobruchus chinensis (Harano and Miyatake 2007), there is no evidence for genetic correlations between males and females for mating speed and/or frequency. Thus our study provides unique empirical support for the theory of Halliday and Arnold (1987).…”

THE EVOLUTION OF REPEATED MATING IN THE BURYING BEETLE,NICROPHORUS VESPILLOIDES

Animals of many species accept or solicit recurring copulations with the same partner; i.e., show repeated mating. An evolutionary explanation for this excess requires that the advantages of repeated mating outweigh the costs, and that behavioral components of repeated mating are genetically influenced. There can be benefits of repeated mating for males when there is competition for fertilizations or where the opportunities for inseminating additional mates are rare or unpredictable. The benefits to females are less obvious and, depending on underlying genetic architecture, repeated mating may have evolved as a correlated response to selection on males. We investigated the evolution of repeated mating with the same partner in the burying beetle Nicrophorus vespilloides by estimating the direct and indirect fitness benefits for females and the genetics of behavior underlying repeated mating. The number of times a female mated had minimal direct and no indirect fitness benefits for females. The behavioral components of repeated mating (mating frequency and mating speed) were moderately negatively genetically correlated in males and uncorrelated in females. However, mating frequency and mating speed were strongly positively genetically correlated between males and females. Our data suggest that repeated mating by female N. vespilloides may have evolved as a correlated response to selection on male behavior rather than in response to benefits of repeated mating for females.

“…Bidirectional artificial selection for female remating receptivity has produced direct responses, with females selected for higher receptivity being less resistant to remating than those selected for lower receptivity (Harano & Miyatake, ). Female remating receptivity has been shown to be correlated with mating frequency within a given period (Harano & Miyatake, ). A previous study showed that C. chinensis females housed with males had lower fitness than those that were isolated from males after mating once (Rönn et al ., ).…”

Receptive females mitigate costs of sexual conflict

Males typically gain fitness from multiple mating, whereas females often lose fitness from numerous mating, potentially leading to sexual conflict over mating. This conflict is expected to favour the evolution of female resistance to mating. However, females may incur male harassment if they refuse to copulate; thus, greater female resistance may increase costs imposed by males. Here, I show that the evolution of resistance to mating raises fitness disadvantages of interacting with males when mating is harmful in female adzuki bean beetles, Callosobruchus chinensis. Females that were artificially selected for higher and lower remating propensity evolved to accept and resist remating, respectively. Compared with females that evolved to accept remating, females that evolved to resist it suffered higher fitness costs from continuous exposure to males. The costs of a single mating measured by the effect on longevity did not differ among selection line females. This study indicates that receptive rather than resistant females mitigate the fitness loss resulting from sexual conflict, suggesting that even though mating is harmful, females can evolve to accept additional mating.
