Fluctuating asymmetry (FA), is a form of biological asymmetry, ... For example, men with higher facial asymmetry experienced higher levels of depression compared to men with lower facial asymmetry. Fluctuating asymmetry has also been studied in relation to psychopathy. One study looking at offenders and non … See more Fluctuating asymmetry (FA), is a form of biological asymmetry, along with anti-symmetry and direction asymmetry. Fluctuating asymmetry refers to small, random deviations away from perfect bilateral symmetry. … See more Developmental stability is achieved when an organism is able to withstand genetic and environmental stress, to display the bilaterally symmetrical traits determined by its developmentally programmed phenotype. To measure an individual's developmental … See more Mate attraction Symmetry has been shown to affect physical attractiveness. Those with lower levels of fluctuating asymmetry (FA) are often rated as more attractive. Various studies have supported this. The relationship … See more Fluctuating asymmetry (FA) can be measured by the equation: Mean FA = mean absolute value of left sides - mean absolute value of … See more Fluctuating asymmetry (FA) is often considered to be the product of developmental stress and instability, caused by both genetic and environmental stressors. The … See more Susceptibility to diseases Research has linked higher levels of fluctuating asymmetry (FA) to poorer outcomes in some … See more Intelligence Through research, fluctuating asymmetry (FA) has been found to have a negative correlation to measurements of human traits such as working memory and intelligence, such that individuals showing greater asymmetry … See more WebMar 27, 2024 · Fluctuating asymmetry is the most studied and has become a measure of DI, especially because it is the easiest to visualize in populations due to differences in the left-right sides (L-R). However, it is a matter of debate which stressors trigger DI during ontogeny and whether genetics alone, or together with the environment, play a role in ...
