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.
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. Webcharacteristics associated with attractiveness is uctuating asymmetry (FA) (Foo et al., 2024; Grammer & Thornhill, 1994; Scheib et al., 1999). FA refers to small random deviations from perfect symmetry in normal bilateral traits in a popula-tion (van Valen, 1962). It has been suggested that lower levels of FA signal the
WebFluctuating asymmetry measures derived from quantitative parameters (finger ridge counts, a-b ridge counts and palmar angles) were analyzed. RESULTS: Fluctuation asymmetry measures were significantly higher in female patients of carcinoma of breast for the thumb (FA = 2.01), subtotal ridge count (FA = 2.10) and for palmar atd angle (FA = … 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
Webthe ME in FA estimates is not a simple sum of the ME for the sides but is most often an order of magnitude higher. Furthermore, even though there is a correlation between Table 3.
