Relatives of persons who commit a sex crime are at increased risk of committing similar crimes, according to a new study from Karolinska Institutet SVT writing about.
It is not about a transferable sexbrottsgen, but that risk factors can be passed genetically.
A new study shows that close relatives of people convicted of sex offenses are more likely to themselves committing similar crimes. The study was conducted among nearly 22,000 men who committed various sexual abuse between 1973 and 2009.
– It turns out that close relatives of people convicted of sexual abuse themselves committing similar crimes, more often than the normal population, says Niklas Långström, researchers at Karolinska Institutet, the Swedish Television News.
The researchers focused primarily on fathers and brothers convicted and compared the full- and half-siblings on the father’s and mother’s side, type SVT.
– These are five times more brothers or sons of convicted offenders sentenced to sex crimes, compared with the normal population, says Långström to SVT News.
No gene
It is not about any sexbrottsgen, he says. Instead, the risk factors are hereditary.
– For example, poor impulse control, propensity to think I have a right to do what I want at the expense of others, sexual preoccupation, and so on. This is the kind of thing that we know is genetically determined, but this is in fact, important enough, factors that one also can do something about, say, Långström, SVT News.
