Why is fluctuating asymmetry a useful indicator of stress?
One such measure is fluctuating asymmetry. Fluctuating asymmetry (FA) is defined as random deviations in the expression of normally bilateral characters and is generally ascribed to ‘developmental accidents’ or noise. The empirical calculation of fluctuating asymmetry is straightforward.
Mar 27, 2021 · Summary. Fluctuating asymmetry plays a pivotal role in mate choice, sexual selection, heritability, and conservation. To date, a broadly available literature portrays the importance of environment and genetics as a trigger of developmental instability, thus leading to higher degrees of FA in bilateral organisms.
Abstract. Fluctuating asymmetry consists of random deviations from perfect symmetry in populations of organisms. It is a measure of developmental noise, which reflects a population’s average state of adaptation and coadaptation.

Fluctuating Asymmetry. Fluctuating asymmetry (FA) is defined as nondirectional variation between left and right sides of a bilateral character and it may arise as a result of an inability to control development under genetic or environmental stress. From: Encyclopedia of Environmental Health (Second Edition), 2019
Mar 5, 2013 · Fluctuating asymmetry (FA), i.e. small, random deviations from perfect symmetry in otherwise bilaterally symmetrical traits, is widely regarded as an individual-based proxy of environmental and genetic stressors in a variety of taxa (e.g., [1] – [5] ).

Fluctuating asymmetry, the random deviation from perfect symmetry, is a widely used population-level index of developmental instability, developmental noise, and robustness. It reflects a population’s state of adaptation and genomic coadaptation. Here, we review the literature on fluctuating asymmetry of human populations.
