Fig. 1: Schematic of the experimental procedure and cross-fostering of pups.

A Timeline of experimental procedure on F0 generation males and cross-fostering of pups. Orange arrow, start of behavioral experiments on F1 generation. See Supplementary figure 1 for a detailed description of the behavioral tests performed on F0 males. B Experimental timeline of behavioral tests performed on the F1 males. C For cross-fostering, the pups were divided into four groups—(i) Control–Control - born to and raised by the same dam, paired with a control male, (ii) Control-PPS—born to a dam paired with a PPS male, but fostered with a dam paired with a control male, (iii) PPS-Control—born to a dam paired with a control male, but fostered with a dam paired with a PPS male and (iv) PPS–PPS—born to, and raised by the same dam, paired with a PPS male.
