Abstract

Parameters of open-field behavior measures are reported for 12 inbred strains of laboratory rats: ACI, A990, A35322, F344, INR, IR, MNR, MNR-a, MR, TS1, TS3, and WAG. Strain differences were highly significant. Genetic drift in defecation is attributed to selection pressures. An analysis of covariance was used to obtain genetic and environmental correlations. The results suggested that any genetic factors underlying the relationship between defecation and ambulation in the open field involve physiological mechanisms that are different from those mediating environmental effects. © 1972, The Psychonomic Society, Inc..
