"Genes with low probability of getting married" and "Drugs that can avoid the crisis of divorce"

There is a gene "AVPR1A" that determines whether or not to prefer monogamy, and it became clear that a certain type of male doubled the probability of experiencing a crisis of divorce or separation, Furthermore, the man who owned this gene naturally said that the proportion of marriage was generally low.

The action of this gene was discovered by Mr. Hasse Walum and his colleagues using twin and offspring studies in Sweden (TOSS) operated by the laboratory of Karolinska University in Stockholm, Sweden. Over 550 twins And what they know from their partner or spouse data. Extreme story, if you can do something about the specific type of this gene, it may be possible to develop a medicine that can avoid the crisis of divorce in the future.

Details are as below.

According to this research result, in the case of a person having a version called "334" or an allele among the gene "AVPR1A", the proportion of not being married seems to be high. In addition, in the case of a wife who married a man who has a specific type of this gene, the rate of feeling not satisfied with married life is high, according to Hasse Walum, a graduate student of medical epidemiology and biostatistics Women who married men who have one or two copies of a particular type of this gene were not satisfied with the married life than women who married men who do not have them on average " .

Of course there are many reasons why marriage relationships are not going well, but this is the first time that the possibility that a specific genotype is involved has been discovered.

In addition, the same gene is present in voles, and according to an early study, this gene has led to making animals more "monogamous" by boosting the level of vasopressin in the brain , It is said that human beings have been found to be similar.

By the way Walum says that it is not possible to predict whether or not to divorce in the future using this gene with arbitrary precision.

For this "AVPR 1 A" we know the following things in the past as well.

In the study of the Hebrew University in Jerusalem, it seems that a relationship between ruthless behavior and the gene called AVPR1a was discovered (Nature News article). It is said that hormone called vasopressin is involved in human social behavior, and examination of AVPR1a which produces the receptor of vasopressin examined that association was found between the length of this gene and ruthless behavior about. For research, a game called "Dictator Game" used in experimental economics was used. In this game, it is possible for players to take altruistic actions or take dictatorship actions and are used to disprove human self-oriented economic activities. When examining the genes of more than 200 subjects, the AVPR1a gene seems to have been shorter in those who take ruthless, self-centered behavior. Moreover, there was no particular difference depending on gender.

Before breaking ...: compassionate gene

The topic that a relationship between a tendency to give generous money to a person and a gene was discovered. Thirty-three subjects submitting genes gave themselves a game on their computer and measured the tendency to divide themselves into fellows without incorporating points by themselves. As a result, those who have a certain feature on the gene called AVPR1a are those who do not have that feature About 1.5 times that of the tendency to share with people.
