These findings support the recent literature, … Web1 apr. 2010 · The small, random imperfections in bilateral symmetry are called “fluctuating asymmetry” (FA), because the direction of the size difference is free to vary [ 9 ]. Individuals are presumably buffered against such developmental insults by employing homeostatic mechanisms to produce the ideal phenotype [ 10 ].
