Genomic linkage of male song and female acoustic preference QTL underlying a rapid species radiation.

ABSTRACT: The genetic coupling hypothesis of signal-preference evolution, whereby the same genes control male signal and female preference for that signal, was first inspired by the evolution of cricket acoustic communication nearly 50 years ago. To examine this hypothesis, we compared the genomic location of quantitative trait loci (QTL) underlying male song and female acoustic preference variation in the Hawaiian cricket genus Laupala. We document a QTL underlying female acoustic preference variation between 2 closely related species (Laupala kohalensis and Laupala paranigra). This preference QTL colocalizes with a song QTL identified previously, providing compelling evidence for a genomic linkage of the genes underlying these traits. We show that both song and preference QTL make small to moderat
