The reason your marriage is plagued by extreme highs and lows may lie in your DNA, a study claims.
The study found that variations in the serotonin-regulating gene 5-HTTLPR correlated with study participants’ relationship fulfillment. Each of our parents pass us a copy of the gene, which can either be short or long. Participants with two short 5-HTTLPR were most unhappy in their marriages in the face of negative emotion, like contempt, but also happiest when positive emotions like humor were present. On the other end of the spectrum, participants with two long copies were satisfied with their marriages regardless of the emotional atmosphere.
