WebMar 20, 2006 · The small, random deviations from perfect symmetry that result from such factors are termed fluctuating asymmetry (FA). 'Fluctuating' refers to a pattern of bilateral variation where variation on the right and left sides is both random and independent. It tends to be small (around 1% of trait size or less). WebFluctuating Asymmetry. Fluctuating Asymmetry (FA) is the deviation from perfect bilateral symmetry in an organism. The more symmetrical an organism is, the better they are at handling developmental stress arising from environmental stress, genetic problems and developmental instability. Along with developmental stability, FA indicates the ...
