Fluctuating asymmetry fa
WebJan 7, 2015 · Such distributions are commonly divided into three types of asymmetry: Fluctuating asymmetry (FA), directional asymmetry (DA) and antisymmetry . Fluctuating asymmetry is usually defined as small and random deviations in the symmetry of bilateral characters of organisms, with a mean equal to zero and variation normally distributed … Webcriteria for ideal fluctuating asymmetry, and an open mind about alternative hypotheses. We review these requirements and try to clarify why they are so essential. Studies of fluctuating asymmetry face a number of serious challenges: a) random phenotypic variation arises for reasons other than developmental instability, b) all descriptors of FA
