A new study from China proposes the 5-HT1A genes may be linked to chances of being in a stable relationship.



            Three researchers in China proposed the theory of the 5-HT1A having a corresponding linked on how an individual behaves when around a significant other. In simpler terms individuals that are bad in relationships, such as those that have frequent break ups.  Difficult to believe that besides the previous beliefs that looks, economic standings, and personality was a huge factor in engaging in a relationship, there was also a hidden factor, a gene that can be passed down from the parents. In a paper titled, “The Association between romantic relationship status and 5-HT1A genein young adults, ”published in scientific reports. They stated that the G allele of a polymorphism labeled-1019G is able to increase the 5-HT1A genes to express more and this has a correlation with the individuals by having an increase in discomfort with close.
Individuals with CG/GG genotypes has a higher chance of being single then a persons with a CC genotype. 
The study they conducted with 579 Chinese undergraduate student resulted by students that have the "G gene" are most likely to have relationship issues and be single more longer and often. The result showed that gender is not a large factor, and the study showed that about 50% individuals without the G gene were in a relationship, 39% with a CG/GG were in a relationship and within the 39%, approximately 5% of them had GG genes. What was interesting was they were able to get the DNA of the students through their hair follicle cells and use a Chelex-100 method.   
The researchers are taking a step forward of understanding the concept of love and why some people prefer to go against the instinct of finding a signifiant other and reproducing. Could also help in understanding why some people like other, that for some would never even consider.
