Fighting genes may be passed from parents to their offspring while behavioral issues in children are not due to marital disharmony. This was disclosed by a research conducted by University of Virginia along with few universities in U.S.
This study had observed 1045 adult identical and fraternal twins and their 2051 children. According to this study, the trait of arguing with one's partner is passed on to their children and this may pose a threat of causing behavioral problems in children like lying, shoplifting, bullying etc.
These findings have been published in the journal, 'Child Development'. The chief scientist K Paige Harden who led this research said that their research could help in treating behavioral problems in children.
