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. WebA geometric morphometric method has been proposed to test the fluctuating asymmetry and the developmental stability of Betula pendula Roth populations. The main factors affecting the developmental stability were the industrial emission level, the relief altitude, and the interaction of both these factors. A strong correlation between the fluctuating …

WebMar 9, 2015 · 1. Introduction. Fluctuating asymmetry (FA) refers to the subtle, random, differences between right and left values of otherwise perfectly symmetrical bilateral traits of organisms [1,2].FA is distinguished from other forms of asymmetry in bilateral traits by the pattern of variation of right-minus-left (R-L) values [2–4].FA occurs when R-L variation … WebFluctuating asymmetry (FA) refers to random, small deviations from perfect bilateral symmetry in morphological traits. These minor deviations from the ideal phenotype reflect environmental and genetic perturbations experienced during ontogeny. FA has been associated with negative health outcomes and many developmental disorders in humans. WebSep 1, 1991 · The term fluctuating asymmetry (FA) refers to randomly produced deviations from perfect symmetry of bilateral traits, and is called fluctuating because the direction of fluctuation is not... cistern\u0027s 7n
