Population-level mating patterns and fluctuating asymmetry in swordtail hybrids.

Die Naturwissenschaften - 1 Aug 2013

Culumber Zachary W, Rosenthal Gil G

Abstract excerpt

Morphological symmetry is a correlate of fitness-related traits or even a direct target of mate choice in a variety of taxa. In these taxa, when females discriminate among potential mates, increased selection on males should reduce fluctuating asymmetry (FA). Hybrid populations of the swordtails Xiphophorus birchmanni and Xiphophorus malinche vary from panmictic (unstructured) to highly structured, in which...
