Illustration of pup scattering in the home cage during the maternal behavior assay. Significantly more dnFGFR dams had pups scattered around the cage during behavioral testing (B and C) than control dams (A and C). Control n = 12 and dnFGFR n = 14 dams. Bars represent percent of litters found in nest vs. out of nest for each genotype. *p < 0.05 compared to control.
