The genetics of speciation: genes of small effect underlie sexual isolation in the Hawaiian cricket Laupala.

Journal of evolutionary biology - 1 May 2011

Abstract excerpt

Sexual behaviours often evolve rapidly and are critical for sexual isolation. We suggest that coordinated sexual signals and preferences generate stabilizing selection, favouring the accumulation of many small-effect mutations in sexual communication traits. Rapid radiation of a sexual behaviour used in signalling, song pulse rate, has been observed in the Hawaiian cricket genus Laupala. Using marker-assisted...
