(A-D) Numbers of offspring from crosses of hAPP-J20 mice with hTau-A152T(L1) (A, B) or hTau-WT(L32) (C, D) mice that were (A, C) or were not (B, D) treated with DOX. (E) Numbers of offspring from crosses of lower expresser hAPP-J9 mice with hTau-A152T(L1) mice that were not treated with DOX. n = 141 (A), 112 (B), 94 (C), 83 (D), and 282 (E) mice per cohort. Yields from two crosses indicated significant deviations from Mendelian inheritance: hAPP-J20 x TRE-hTau-A152T(L1) x CaMKII-tTA without DOX (Holm-adjusted P = 0.003, unadjusted P = 0.0008) and hAPP-J9 x TRE-hTau-WT(L32) x CaMKII-tTA without DOX (adjusted and unadjusted P < 0.0001) by chi-square goodness-of-fit test.
