I would like to determine if there is any relationship at all between Y-chromosomal DNA and aggressive character. It is certain that character, and temperament in particular is highly hereditary. It is also undeniable that the function of the Y chromosome is to promote masculine traits and to produce testosterone. So in all likelihood there should be a link between a man's Y chromosome and how aggressive/assertive he is. In fact, a 2009 study found that Pakistani men belonging to hg R1a or R2 were considerably more aggressive than other Pakistani men (who belonged mainly to hg G, H, J2, and L).
Being aggressive does not just mean being prone to violent behaviour, but also being verbally aggressive, argumentative, uncooperative, stubborn/obstinate, and having a generally more competitive attitude towards others. For kids, natural aggressiveness also translate as being temperamental, being a bad loser, doing the opposite of what one is told, and so on - although this will also depend on the child's upbringing and social environment.
I have the chance (for the purpose of genetic comparisons) to have a large extended family, and I have tested enough male lineages to be able to compare members of at least some haplogroups. My observations make no doubt that R1b boys are/were far more turbulent and aggressive than those of other haplogroups, and hg I in particular (by far the least turbulent or aggressive).
Adults tend to be formatted by their education and influenced by their environment and society. In rich and peaceful countries it usually means that people are less aggressive as adults, or at least have more controlled reactions.
Please mention on a scale from 1 to 5 how aggressive you'd consider yourself as a child/teenager. You can also add male relatives sharing the same Y-DNA or who also tested their Y-DNA line.
1 - very peaceful
2 - more peaceful than average
3 - normal, average
4 - more aggressive than average
5 - very aggressive
