The pattern of genetic correlations across the inbred strains suggests that object preference and spontaneous alternation are genetically distinct from each other and largely unrelated to any of the other tasks, whereas activity in a novel environment is correlated with most other measures. This pattern is similar to that obtained from correlating the dependent measures of each mouse from all tests; i.e., the phenotypic correlations among dependent measures are similar to the genotypic correlations (see Table 4).
