The genetics, life-history, and behavior of swordtails and platyfishes (Teleostei: genus Xiphophorus) have made these small fishes an important model in evolutionary biology. Most behavioral research has focused on sexual communication: males competing for mates and females choosing from among potential partners. Sexually dimorphic traits in Xiphophorus show considerable variation within and across species, are under both natural and sexual selection, and in some cases, are controlled by simple genetic mechanisms.

Abstract
The genetics, life-history, and behavior of swordtails and platyfishes (Teleostei: genus Xiphophorus) have made these small fishes an important model in evolutionary biology. Most behavioral research has focused on sexual communication: males competing for mates and females choosing from among potential partners. Sexually dimorphic traits in Xiphophorus show considerable variation within and across species, are under both natural and sexual selection, and in some cases, are controlled by simple genetic mechanisms. These features have yielded important insights into how animal communication systems evolve. Recent research on Xiphophorus has begun to shed light on the evolutionary genetics of communication signals and mechanisms of mate choice.Pubblicazioni consigliate
