Webtuating asymmetry refers to these directionally random, subtle departures from perfect symmetry and is hypoth-esized to indicate the inability of an organism to maintain precise development (Palmer and Strobeck 1986). Fluctuating asymmetry variance of populations and ab-solute FA values of individuals has been found to increase WebThis trait is often referred to in the literature as Fluctuating Asymmetry (FA), referring to the origins of asymmetry in deviations (fluctuations around) mean differences of zero. In the present article, for ease of understanding, we refer to symmetry rather than FA.
WebFluctuating asymmetry (FA) refers to small random differences between the left and right sides of bilateral characteristics (Van Valen, 1962; Palmer & Strobeck, 1986; Møller, 1990).
