Nachman and Heller recently suggested that previous estimates of the relative magnitude of fluctuating asymmetry in morphological characters have been biased because non-linear relationships between asymmetry and size have not been considered. This suggestion cannot generally be very important because (1) inclusion of a non-linear size term in regression models relating fitness components to asymmetry does not change the general conclusion that asymmetry is an important predictor of fitness components, and (2) experimental studies uncoupling the relationship between asymmetry and size have generally found significant effects of asymmetry independent of body size on mating success and locomotion.
