Genes may explain why children who live without dads have earlier sex
Date:9/14/2009

bsence and early sex.

"While there's clearly no such thing as a 'father absence gene,' there are genetic contributions to traits in both moms and dads that increase the likelihood of earlier sexual behavior in their children," notes Mendle. "These include impulsivity, substance use and abuse, argumentativeness, and sensation seeking.

"These traits get passed down from parents to children, resulting in a situation known as 'passive gene-environment correlation,' because the same genetic factors that influence when children first have intercourse also affect the likelihood of their growing up in a home without a dad."
