If you find yourself permanently single whereas all others around you are in a relationship, there is a problem with your DNA. Scientists from Peking University in Beijing have discovered that people who have the ‘singleton gene’, are 20 per cent more likely to be single than others.

Scientists concluded that by lowering levels of the feel-good brain chemical serotonin, the gene makes people less comfortable in close relationships. Means forming a relationship can be harder – while that could also lead to break-ups.

Hair samples from almost 600 Chinese university students were tested to analyze a gene called 5-HTA1, that has two different variants. It was found that people carrying the ‘G’ version were much more likely to be single than those with the ‘C’ version. Some 60 per cent were not in a relationship – compared to 50 per cent of those in the c group.

Importantly, the connection couldn’t be explained by other characteristics that influence relationships, including appearance and wealth. The role of the 5-HTA1 gene in the brain appears to be the key to the findings. People who carry the ‘G’, or singleton, version produce less serotonin, a brain chemical associated with mood and happiness. It was found that it was harder for people with the ‘G’ allele, or version to get close to others. As well as, they tend to be neurotic and usually suffer from depression

Writing in the journal Scientific Reports, the researchers said: ‘As pessimism and neuroticism are detrimental to the formation, quality and stability of relationships, this connection between the G allele and psychological disorders might decrease carriers’ dating opportunities or lead to romantic relationship failure.’

The researchers opined that students may have ample free time and freedom to form relationships than others. And at other times of life, factors such as pressure from parents to marry may be a great deal more influential. Regardless of this, they deduced that their study provides ‘evidence for genetic contribution to social relationships in certain contexts’.



As per another controversial study of Harvard Business School graduates, a large percentage of women put their husband’s career before their own. The study canvassed about 25,000 male and female students, and discovered that 40% of Generation X and ‘boomer’ women said their spouses’ careers took priority over theirs. Researchers stated that just 20% of the women had planned on their careers taking a back seat when they graduated.
