Social dominance: HET and KO mice are more dominant than CTR mice. In the tube test, 1 was the most common rank among both HET and KO mice, whereas 3 was the most common rank among CTR mice (A). Ranks remained very stable over time. (B) shows the development of the mean rank over time for three groups of mice based on their rank reached in the first test, whereas (C) shows the development of the mean rank per genotype over time. Of all their interactions, HET, KO and CTR mice won 82.9, 54.7, and 16.7%, respectively (D). (n = 5 CTR, 4 HET, 5 KO). (###p < 0.001).
