Performance of animals in odor-salience test. Female and male rats have the ability to discriminate odors regardless of their lineage. (A) Both sexes show similar patterns, exploring odors of the opposite sex more than odors of unfamiliar individuals of the same sex or their own familiar odor. Data are expressed as mean percentages of total exploration time (± 1 SEM). (B) EDC-lineage males spend significantly more time exploring control- than EDC-lineage female odors. EDC-lineage females spend significantly more time exploring the odor of a novel EDC- than of a novel control-lineage male.
