- Number of female mice in the home-cage activity study: B6, N = 10; KJR, N = 10; B6xKJR F1, N = 11; B6xKJR F2, N = 274. THA, total home-cage activity (× 103); AT, active time (× 102); AA; parentheses indicate standard deviation; broad-sense heritability H2 is calculated as follows; H2 = (Variance of B6xKJR F2 - Variance of B6xKJR F1)/Variance of B6xKJR F2. Asterisks indicate significant difference between B6 and KJR or B6 and B6xKJR F1. Double asterisk indicates significant difference between KJR and B6xKJR F1.
