Figure 1. Mating behavior of the female offspring and the effect of cross-fostering.

Figure 1

(a) Tested with a stud male in a small traditional testing arena, the mean (±SEM) lordosis rating in the adult female offspring of High LG mothers was lower compared to Low and Mid offspring (n = 10–12/group).* p<0.05. (b) Tested in a pacing chamber, the mean (±SEM) lordosis rating of adult female offspring of High LG mothers was lower compared to Low female offspring. * p<0.05. The inter-intromission interval showed no significant differences (n = 12/group). (c) Mean±SEM lordosis rating or inter-intromission interval in the adult female offspring of Low or High LG mothers fostered to and reared by Low (Low-Low; High-Low) or High (Low-High; High-High) tested with a stud male in the pacing chamber (n = 7–13/group). Groups lying underneath the line differ significantly (p <0.05) from the Low-Low group. (d) Mean±SEM testosterone level in amniotic fluid of embryonic day 20 female offspring of High or Low LG mothers (n = 20–25 pups from 12–14 litters/group; *p<.01).
