Bursting into laughter easily could be in your DNA
If your wife immediately bursts into laughter after a humorous moment, while you barely manage to crack a smile, this could be due to her genes, new research says. The researchers demonstrated that people with a certain genetic variant smiled or laughed more while watching cartoons or subtly amusing film clips than others.
New York: If your wife immediately bursts into laughter after a humorous moment, while you barely manage to crack a smile, this could be due to her genes, new research says. The researchers demonstrated that people with a certain genetic variant smiled or laughed more while watching cartoons or subtly amusing film clips than others.
Those with short alleles of the gene 5-HTTLPR smiled more than people with long alleles, the findings showed.An allele is a variant of a gene. Each gene has two alleles; humans inherit one allele from mother and one from father. "The short allele amplifies emotional reactions to both good and bad environments," said study author, Claudia Haase from Northwestern University in the US. Specifically, people with the short allele displayed greater genuine smiling and laughing than people with the long allele.
