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 … WebSep 7, 1998 · 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.
