Abstract
Early imprinting was studied under laboratory conditions in five lines of mallards (Anas platyrhynchos) with different degrees of wildness obtained through pedigreed breeding. Data were analyzed by the least squares method. Wild ducklings imprinted better than game-farm (domesticated) ducklings, and heterosis was demonstrated to exist in imprinting traits. Nonadditive genetic variations and genotype-environmental interactions are discussed as possible causes for the heterosis observed. Differences in imprinting between genetic lines are attributed, at least partly, to differences in arousal level during the ducklings' first exposure to the imprinting stimulus.
