Figure 4. Cross-fostering reversed, and fatherless rearing diminished, female song preference.

Figure 4

(a) Experimental scheme of the cross-fostering paradigm. Part of the litter (B6-fosterer and BALB-fosterer) was reciprocally cross-fostered to parents of the other strain of mice. (b–e) B6 sister (n = 10) and BALB-fosterer (n = 15) showed longer search times for BALB song. In contrast, B6-fosterer (n = 16) and BALB sister (n = 14) treated with ESP1 prior to the experiment showed longer search times for B6 song. GLM with fosterer/sister and male song as factors revealed significant effects of the interaction. (f) Fatherless B6 and fatherless BALB ware raised by mothers only. (g–h) There was no significant difference in search time for B6 and BALB songs in fatherless B6 and BALB females. Values represent means+standard error. Asterisks indicate significant differences p<0.05.
