Sex offending may be in the genes but knowing that won't prevent it

"The implication is that the potential for committing a sex offence may be written in our genes. But while this is an interesting finding, it is unlikely to help prevent sex crimes or catch offenders.

The research, which analysed DNA from 21,566 men convicted of sex offences in Sweden between 1973 and 2009, found that sons and brothers of convicted sex offenders were four to five times more likely to be convicted of sex crimes than men in the general population. In seeking to explain this connection, the researchers found that in only 2% of cases could this familial connection be explained by shared environmental factors, such as social or environmental aspects of their upbringing that siblings would have experienced together."
