WebNov 19, 2024 · Development instability (DI) refers to slight and random deviations to perfect left-right symmetry in structures, and is classically measured as fluctuating asymmetry (FA). In different taxa, excess of FA could be associated with (human-mediated) genetic [ 6 – 10 ] and environmental [ 11 – 14 ] stresses, and reduced adaptive value or ... Webfluctuating asymmetry and that a relationship between asymmetry and individual quality cannot be assumed.

WebAbstract: Fluctuating asymmetry is mainly interpreted as an indicator of developmental instability, while directional asymmetry of the upper limbs is associated with handedness. The association patterns between adult androgen levels and fluctuating as well directional asymmetry patterns are still unclear.
