It’s a honeymooner just looking at each other, but marriage satisfaction will vary for each individual. How satisfied are you with your honeymoon? Do you know that the secret to that happiness lies in your genes?
A team of professors at the Department of Psychology, Anastasia Macanova, University of Arkansas, studied 71 couples (a total of 142) newlyweds, and found that certain genetic mutations seem to affect the satisfaction of their newlyweds. (Nature Scientific Reports).
Based on the genotype data of 71 newlyweds, the researchers analyzed the relationship between the’CD38′ gene mutation and the newlyweds’ mutual trust, forgiveness, and marital satisfaction.
♦’Thank you gene’ CD38, the secret to a happy newlywed life
‘CD38′, a gene related to the secretion of oxytocin, is also called a’thank you gene’, and it is known that people with strong this gene are satisfied with their relationships and have a lot of positive emotions. In this study, the results of marriage satisfaction according to the CC mutation, AC or AA mutation in the CD38 gene were reported.
The DNA of newlyweds, the subject of the study, was collected 3 months after marriage, and was asked to answer a questionnaire on marital life and spouse satisfaction every 4 months for 3 years after marriage. After the study period, the researchers compared and analyzed the collected CD38 gene mutations and the survey results.
As a result of the final analysis, the CC mutation of the gene CD38 was found to be a genotype that influences the reliability of the newlywed relationship, and those with the CC mutation in the CD38 gene showed higher satisfaction with marriage.
People with the CC mutation were more grateful to their spouse than those with the AC or AA mutation genotype and had a higher sense of trust. They also showed higher levels of forgiveness and higher satisfaction with their marriage as a whole.
Overall, people with the CC mutation gene of CD38 formed a high level of trust between couples, and based on this, they maintained a successful marital relationship.
Prof. Markanova said, “In general, marriage satisfaction tends to be high at an early stage and then gradually decrease. As one of the reasons for having difficulty maintaining consistent relationship satisfaction, genetic factors seem to have a potential effect.”
“However, just because the CC mutation of CD38 does not exist does not mean that a successful relationship cannot be formed in marriage, it should not be interpreted as a single point that people without the CC genotype will have problems in the marriage relationship.”
