Figure 7. Somatic growth.
Representative photograph of the body size differences between a pnd 2 BTBR (upper pup) and a pnd 2 B6 (lower pup). Analysis of the markers of somatic growth revealed that BTBR displayed accelerated development as compared to B6 on A) body weight, B) body and C) tail length, D) pinnae detachment, E) opening of the eyes and F) incisor eruption. Figures 7– 10 present results from Cohort 2, N = 20 B6 and N = 20 BTBR, representing one male and one female from each of 10 litters per strain. ** p<.01 and *p<.05, for B6 vs. BTBR.
