5-HTTLPR. That may sound gibberish to most of you, but it’s the serotonin-transporter-linked polymorphic region. More confused? Let’s put it simply: it’s the gene involved in the regulation of serotonin, that hormone that claims to make us happy.
Now that all the verbosity is out of the way, here’s the lowdown: people with two short 5-HTTLPR alleles were found to be much more sensitive to the emotional tone of their marriage, in a new study. What does this mean? Those with two short 5-HTTLPR alleles tend to blossom when the emotional tone of their marriage is good, much like a sunflower that gets just the right amount of sunlight and water, and tend to wither when they aren’t fed with enough of these essential elements. For those with one or two long alleles, the emotional tone of the marriage had little or no effect on their satisfaction with the marriage.
