fluctuating asymmetry

https://doi.org/10.1351/goldbook.14696
Deviation from perfect bilateral symmetry for a population of a bilaterally symmetrical species that is thought to reflect developmental instability.
Note: A trait is measured from the right and left sides of each individual, and the variance in the difference (right–left) for the population is a measure of fluctuating asymmetry.
