Chinese researchers are studying the association between romantic relationships and 5-HT1A gene in young adults.
There are obvious factors which influence attraction and relationships between people, such as personality, looks, and intelligence. These researchers are trying to show that genetics may contribute to the development of romantic relationships.
Pair bonding and affective affiliation (romantic behaviors) are shown to be associated with the serotonin levels in the brain. In non-human animals, decreased serotonin via the 5-HT1A gene decreases female sexual receptivity and causes aggression towards males.
The G allele of the C-1019G polymorphism (which leads to greater expression of the 5-HT1A gene) is related to decreased comfort with close/romantic relationships.
How is this related to being in a relationship? To explore this, 579 Chinese undergraduate students were studied. Cells from hair follicles were collected and DNA was extracted.
The results indicate individuals carrying the G allele (CG/GG) of C-1019G were more likely to be single than non-G, CC carriers. This agrees with the finding that G allele carriers are less comfortable in close relationships.
Actually, G allele carriers are more likely to develop psychiatric disorders (major depression, borderline personality disorder, etc.) and neurotic personalities. All of the above can hinder the formation of relationships, as well as their quality and stability. The connection between the G allele and psychological disorders may lead to fewer dating opportunities and/or unsuccessful relationships.
The researchers believe the findings of their study offer evidence that genetics can influence social relationships.
This study is interesting because it offers even more insight about how much genetics affects our lives. There are obvious things like hair color and eye color but the influence of our genes permeates all aspects, even our relationships. This makes sense because other studies (like this one) investigate how our health, which is influenced by our genes, then influences our relationships. It offers hope to people who struggle with making personal connections that we may find a way to help them connect with others around them

It is so weird to think that our genes have such an affect on our relationships with other people. I don't know if I would want to be a participant in this study because I feel like if I found out I was more likely to be single I would blame every relationship I ever had on my genes. Just with the way I am I feel like this could have a negative affect on the way I view relationships and I'm better off not knowing.
