  The study is a genome-wide analysis conducted 3 1932 unique subjects which 4 pairs of unrelated friends and unrelated strangers. The same people were used in both 5 .

  While 1% may seem 6 , it is not so to a geneticist. As co-author of the study James Fowler, professor of medical genetics at UC San Diego says, "Most people do not even 7 their fourth cousins but somehow manage to select as friends the people who 8 our kin."
