Illustration of housing treatments in experiments 1–5. The initiation and duration of opposite-sex (OS) and same-sex (SS) housing in experiments 1–5 are depicted. Thin dark gray bars indicate the duration of SS housing, and the thicker light gray bars indicate the duration of OS housing. Experiments were initiated by housing postnatal day (PND) 30 wild-type (WT) and dnFGFR males with novel age-matched female(s) (black triangle) or male(s) (white circle). Animals were killed for analysis at the end of the housing treatments (indicated by “x”). LP, late paired.
