Abstract

Developmental stability, the ability of organisms to buffer their developmental processes against developmental noise is often evaluated with fluctuating asymmetry (FA). Natural genetic variation in FA has been investigated using Drosophila wings as a model system and the recent estimation of the heritability of wing shape FA was as large as 20 %. Because natural genetic variation in wing shape FA was found to localize in a partial component of the wings, heritable variation in specific parts of the wings might be responsible for FA estimation based on the whole wing shape. In this study, we quantified the shape of three partial components of the wings, and estimated the heritability of the wing shape FA based on artificial selections. As a result, FA values for the partial wing shape components did not respond to artificial selections and the heritability scores estimated were very small. These results indicate that natural additive genetic variation in FA of partial wing components was very small compared with that in a complex wing trait.
