So in sum you’re saying divorce is genetic and home life has little to no impact on the development of personality?
That begs a couple of questions then.
Why was divorce so rare in society until very recently (in terms of the last 400 years or so?)
Why is it the majority of people in prison come from broken homes?
Things is, that according to more recent reasearch, it’s not divorce per se that is necessarily genetic, but rather, other genetic behaviours (such as tendencies towards gambling, alcoholism or infidelity) which lead to divorce. It is, after all, important to remember that marriage is human created, and not a biological issue.
"Dr Lyons believes that environmental factors swamp any genetic influence on marriage because people are generally young when they wed, and their decision rests heavily on the success or failure of their parents’ marriage.
But once in a marriage, other factors kick in.
He thinks the genetic influence on divorce is related to factors such as drug abuse, depression and alcoholism, which have a genetic component.
The team found that twins who were pathological gamblers, for instance, were 2.8 times more likely to get divorced than the norm for the day.
Dr Lyons said: “Almost any kind of psychopathology is going to make staying married harder.” "

Further, an interesting paper compared adoptive children with those raised by their biologic parents, and found :
"In biological families, children who experienced their parents’ separation by the age of 12 years exhibited higher rates of behavioral problems and substance use, and lower levels of achievement and social adjustment, compared with children whose parents’ marriages remained intact.
Similarly, adopted children who experienced their (adoptive) parents’ divorces exhibited elevated levels of behavioral problems and substance use compared with adoptees whose parents did not separate, but there were no differences on achievement and social competence."
This would indicate that homelife is indeed at least partially responsible for development of the individual, and the adoption based studies also lead to that conclusion.
