波动不对称(FA)是衡量个体发展稳定性的一个不完善的指标。对FA遗传力的估计将低估发育稳定性的遗传力；这种偏差的程度可以通过估计发育稳定性的重复性来估计和纠正。本说明纠正了以前使用两侧差异的绝对值作为FA的衡量标准时对这种可重复性的推导中的错误，并推导了FA的另一种常见衡量标准--个体内部两侧之间的差异--的发育稳定性的重复性。
Fluctuating asymmetry (FA) is an imperfect measure of the developmental stability of an individual. Estimates of the heritability of FA will underestimate the heritability of developmental stability; the extent of this bias can be estimated and corrected by estimating the repeatability of developmental stability. This note corrects an error in a previous derivation of this repeatability using the absolute value of the difference between sides as the measure of FA, and derives the repeatability of developmental stability for another common measure of FA, the variance among sides within an individual.
