Abnormal exploratory behavior in Trim28^MommeD9/+ mice. The behavior of 19 Trim28^MommeD9/+ mice and 14 Trim28^+/+ mice was tested in an open field (40 cm × 40 cm). Mice were scored for the number of 10-cm² squares entered (Squares) and the number of times they reared on their hind legs (Rears) in a 2-minute period. *P < 0.05 (t-test and F test), ^†P < 0.0005 (t-test and F test).
