title: Data from: Unravelling mate choice evolution through indirect genetic effects

description: Attractiveness is not solely determined by a single sexual trait but
 rather by a combination of traits. Because the response of the chooser is
 based on the combination of sexual traits in the courter, variation in the
 chooser’s responses that are attributable to the opposite-sex courter
 genotypes (i.e., the indirect genetic effects (IGEs) on chooser response)
 can reflect genetic variation in overall attractiveness. This genetic
 variation can be associated with the genetic basis of other traits in both
 the chooser and the courter. Investigating this complex genetic
 architecture, including IGEs, can enhance our understanding of the
 evolution of mate choice. In the present study on the field cricket
 Gryllus bimaculatus, we estimated (1) genetic variation in overall
 attractiveness and (2) genetic correlations between overall attractiveness
 and other pre- and post-copulatory traits (e.g., male latency to sing,
 female latency to mount, male guarding intensity, male and female body
 mass, male mandible size and testis size) within and between sexes. We
 revealed a genetic basis for attractiveness in both males and females.
 Furthermore, a genetic variance associated with female attractiveness was
 correlated with a genetic variance underlying larger male testes. Our
 findings imply that males that mate with attractive females can produce
 offspring that are successful in terms of pre-copulatory sexual selection
 (daughters who are attractive) and post-copulatory sexual selection (sons
 with an advantage in sperm competition), potentially leading to runaway
 sexual selection. Our study exemplifies how the incorporation of the
 IGE-framework provides novel insights into the evolution of mate choice.
