WebSep 7, 1998 · Abstract Fluctuating asymmetry (FA) refers to deviations from perfect symmetry in a bilateral character and is believed to reflect an organism's quality. However, allometric relations between asymmetry and trait size may confound FA–quality relations. Larger traits may have more ‘opportunity’ to become asymmetric. WebDec 25, 2001 · Relative fluctuating asymmetry (mean and 1 SE) on wings (a) and tarsi (b) of birds from control forests and fragments. I, for all species; II, for species present in both forest types; III, for species present in both forest types with controlled sample sizes. Values refer to the mean FA c (equation 1) among control areas and among fragments.
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. WebJan 1, 1984 · When asymmetry was compared between the various tooth dimensions, the buccolingual dimensions of mandibular incisors consistently displayed high asymmetry values. This finding may reflect a developmental interaction between the deciduous incisor tooth germs and their lingually-placed permanent successors.
