Results of the GEE analyses are depicted in Figure 1 and Table 3. Ancestry proportion scores significantly predicted children’s aggression (χ2 = 11.5; p = .0007) and rule breaking (χ2 = 4.6; p = .03) scores, TTES was also a significant predictor of aggression (χ2 = 4.7; p = .03) and rule breaking (χ2 = 14.3; p = .0002), and MAOA genotype (χ2 = 3.8; p = .05) and MAOA genotype in interaction with TTES (χ2 = 6.2; p = .01) predicted inattention. After controlling for multiple comparisons using Bonferroni corrections, ancestry proportion scores in predicting aggression,TTES in predicting rule breaking and the G×E interaction of MAOA genotype and TTES in predicting inattention remained significant.
