NewScientist reported this week on a University of California research study that analyzed the genes of 3,000 pairs of friends looking for genetic differences or similarities that might indicate a genetic predisposition for certain types of friendships.
The study found that close friends share similarities in the DRD2 gene and are less likely to share similarities in the CYP2A6 gene.
Here’s how the story was reported on ABC News:
