Fluctuating asymmetry refers to:

WebThe most common measure of developmental instability, fluctuating asymmetry (FA) (Van Valen, 1962), refers to normally distributed deviations across planes of organismal symmetry. WebFeb 7, 2024 · And there are two major forms of bilateral asymmetry. In antisymmetry (which can be considered a macroscopic form of “fluctuating asymmetry” see here ), there is no directionality to the trait, so the asymmetry is random with respect to the side of the body.
