Selection for tonic immobility duration does not affect the response to novelty in quail

摘要: Abstract Genetic selection on a single fear test, the tonic immobility seems to result in fearfulness, i.e. propensity exhibit responses, whatever tests used. However, conception of as variable has been challenged by recognition that is multidimensional. This study was designed test whether genetic classic index birds, duration, accompanied changes response dimension – novelty. Two lines quail divergently selected for long (LTI) or short (STI) duration were exposed novel object their home cage. Quail both showed typical reactions novelty but there no difference between lines. We conclude does not affect all dimensions fear, notably Further studies are needed investigate which two could have selected.
