Abstract
GENETIC selection of behavioural characteristics has been observed, among others, in the Maudsley, Roman, and Tryon strain of rats1. Here we describe an experiment designed to test the hypothesis that rats could be selectively bred to win or lose in a food competition situation of the type reported by Lindzey et al.2 with mice and later used by other authors with rats3–8.
