The life of love and affection and our propensity to start relationships and a partner are linked to many elements: The number of people we usually deal with on a daily basis, our social skills, interests, etc.
However, there are indications which show that in addition to the aspects of our personality which are part of us through the experiences that we have had and the learnings that we have made, genetics also influence.
Of course, some of these genetic aspects have to do with how we look and how we fit into certain canons of beauty. But our chances of being in a relationship can also be affected by genes in another way: psychological.
The gene that regulates the onset of relationships
While our health and the appearance of our body influence the extent to which we are predisposed to having a partner, certain aspects of the personality heavily influenced by our genes also play a role.
Of course, it’s always problematic and confusing to study how genetics influence our behavior, but it’s increasingly likely that more is known about the detailed ways our DNA predisposes us to finding a mate. Indeed, a study carried out in 2014 provided some clues about this link linked to the world of love and the couple.
Serotonin and love
There are several hormones produced by the human body that have been associated with bonding affection and love. Serotonin, which also acts as a neurotransmitter in our nervous system, is one of these types of substances.
More precisely, we have seen that an increase in serotonin levels potentiates the onset of sexual desire and actions that express affection (Like looking into each other’s eyes for a long time, caressing or hugging). Plus, it reduces aggression levels.
The genetics behind love
A group of researchers from Peking and Henan universities proposed how the genes behind the mechanisms that serotonin uses to influence our behavior may play a role in the chances of having a partner.
Specifically, they studied the effects they had different variants (alleles) of the 5-HT1A gene, Which, by expressing it, causes the receptors that serotonin uses to trigger processes in organs and neurons to somehow build up.
Carry out research
To conduct the study, the researchers recruited more than 500 students, from whom they took hair samples.
From these DNA samples, they saw that indeed, the fact that each of these people had one variant of 5-HT1A or another had to do with their romantic situation.
People with an allele of the gene called G produced less serotonin than those with the variant called C. This meant that if what was known about serotonin was true, people who had the G allele would be less likely to have a partner.
Was this reflected in the sentimental situation of the volunteers? In fact, about 50% of people carrying the C allele had a partner for this only happened with 39% of carriers of G alleles.
A capricious personality
In addition, people with variant G were more prone to neuroticism and sudden mood swings usuallyAnd they felt less comfortable in intimate situations or with a partner than people with the C allele. Plus, they were also more likely to develop depression.
This tendency to emotional instability it may be more difficult to maintain relationships or that they are not even initiated by the urgent problems to begin with.
Genetics is not everything
Of course, genetics aren’t everything, even if they influence it. This means that having either type of DNA does not make a person predestined to have a partner or that woman single; learning remains a crucial aspect.
Although in theoretical debates learning and genetics are often treated as if they are different things, in reality they always act together: where there is learning there is nothing, and in psychology, these genes are expressed through actions that arise, in part, from learning past.
In this case, for example, people with the G allele may be more likely to be single. not because their DNA prevents them from forming a relationshipBut because by learning, they see that potential couples tend not to match their personalities, which makes them learn not to strive for their satisfaction at all costs.
In this sense, not having a partner is a decision that genes influence, but it is not an unavoidable destination; it is simply the result of a balance between costs and benefits.
