. Fifty‐four per cent of the specimens in a sample of 147 lake whitefish ( Coregonus clupeaformis ) from northern Quebec exhibited a pronounced lack of bilateral symmetry in the distribution of metacercariae of the genus Diplostomum . This asymmetry was shown not to be a product of chance. A comparable degree of asymmetry was generated by a computer simulation incorporating a positive feedback mechanism. The simulation and the biological significance of such asymmetry are discussed.
