Genetics Determine Who Becomes Friends

If you’re having trouble finding friends, blame your DNA.  According to scientists, our DNA contains markers that apparently help foster the bonds of friendship. Could your circle of acquaintances be determined by your genetic disposition?  Perhaps so.

Using two independent studies, the National Longitudinal Study of Adolescent Health and the Framingham Heart Study, scientists have determined that our genetics might determine just who becomes friends with who. Six genetic markers have been identified that help to determine just who becomes friends with whom, or who doesn’t become friends.  DRD2, which is a genetic marker associated with alcoholism, seems to be common in groups of friends.  A second gene, CYP2A6, seems to keep people apart as those with the marker avoid one another.

“That feeling that you get that you’re just going to like somebody or not going to like them – a lot of times we’ll have those instincts about people and we’re not sure where they come from.  We think that understanding the genotypes that underlie friendship may help us to understand more of that process,” says study leader Professor James Fowler of the University of California.  ”It’s not like I’m going to be carrying around a little spit kit and testing all my friends.  It’s those genes’ underlying characteristics which we must be able to detect in some way either consciously or unconsciously.”
