Happy marriage depends on DNA?

Some people say that the secret of a happy marriage is patience or never argue with a bed. However, American psychologists say, the key to sustainable attachment may be in our DNA.

Researchers from the University of California and Northwestern University believe that a gene involved in the regulation of serotonin "happy hormones" can predict the impact of our emotions on with emotional relationships. This may be the first study to link genetics and emotions to the level of marriage satisfaction.

The team looked at the genetic pattern of more than 100 couples and observed how they interacted with their partners over time.

They found a relationship between marital status and a gene variant or allele called 5-HTTLPR . Everyone inherits a copy of this gene variant from their parents.

The team found that, in marriage, those who own two 5-HTTLPR alleles are often least happy when there are many negative emotions such as anger and disdain, but happiest when they have emotion. extreme like humor and love. In contrast, those who own one or two 5-HTTLPR alleles seem to be less affected by the daily emotional changes in their married life.

The researchers stressed that the discovery did not mean that couples with different 5-HTTLPR gene variants did not get along. Instead, it implies, those who own short alleles are more likely to prosper in a warm and exhausted marriage if they fall into a bad marriage.
