Association between the impulsive aggressive behaviors and the heterozygosity of 1 7 short tandem repeats loci

Abstract

Objective To investigate the relationship of the impulsive aggressive behavior and the heterozygosity of 1 7 short tandem repeats （ STRs ） loci .Methods The biological samples of 2 4 9 army-men with impulsive aggressive behavior and 3 1 3 healthy armymen without aggressive behavior were collect-ed .Then all of the sample were amplified by PowerPlex 1 8 D System and separated by electrophoresis to obtain the heterozygosity of 1 7 STRs loci in both groups .Results All the 1 7 STRs loci in both groups were found to coincide with Hardy-Weinberg equilibrium; The ratios of heterozygotes with in the 1 7 STR loci in both groups were not different （ P =0.5 3 3 ）;The heterozygosity of CSF 1 PO locus within armymen with impulsive aggressive behavior was lower than control group （ P =0.0 3 5 ）; The heterozygosity of both groups was not different in the other STR loci （ P 〉0.0 5 ） .Conclusion The reduction in heterozygosity of CSF 1 PO might associated with impulsive aggressive behavior .
