Mice trained to discriminate urine odors of mice differing in both the MHC and in diet generalized this response to diet changes but not to MHC.

Diet: Diet S = Synthetic diet; Diet L = Laboratory Rodent diet.

^†

on training trials reinforced to go to B6 Diet S over B6-H2^k Diet L.

^‡

on training trials reinforced to go to B6-H2^k Diet S over B6 Diet L.

^§

p<0.0001, binominal test.

The plus sign (+) refers to a choice that is correct or concordant with training whereas the minus sign (−) refers to a response that was incorrect or not concordant with training.

The numbers in the tables represent the generalization trials only.
