Mechanisms that drive variation in female mating preferences in Xiphophorus malinche

Abstract Details

2007, Master of Science (MS), Ohio University, Biological Sciences (Arts and Sciences).
In Xiphophorus malinche, larger, older females prefer asymmetrical males while smaller, younger females prefer symmetrical males. Mating experience has been shown to alter female preferences. I examined whether copulatory experience as well as experience with males of different symmetry affected female preference for symmetry in X. malinche. Male aggressive behaviors and male preferences may affect female experience, thus influencing female preference. I examined whether male aggression and male preferences for female size varies with symmetry. Female size at maturity and female experience affected female preference for symmetry suggesting a genetic and environmental component exists for preference for symmetry. Male mating preference for female size did not vary with symmetry and is not likely to affect female preferences. The less aggressive response by symmetrical males to the symmetrical image and their overall lower frequency in the field could play a role if females perceive symmetrical males as less aggressive.
