Fluctuating Asymmetry: A Technique for Measuring Developmental Stress Caused by Inbreeding

Abstract

Fluctuating asymmetry has sometimes been employed to indicate disruption of developmental homeostasis. Such disruption is thought to be a result of increased developmental stress. In this study we examine the relationship between fluctuating asymmetry and inbreeding level in two differing breeding systems: the marine harpacticoid copepod Tisbe holothuriae, a typically outbreeding diploid, and the common honeybee Apis melli/era, which is haplo-diploid. Inbreeding has previously been shown to constitute a developmental stress in populations of T. holothuriae, but the same is yet to be conclusively shown in A. melli/era.
