friendsJan 19, (THAINDIAN NEWS) They say, a friend in need is a friend indeed. How do we make friends? Why do we like someone? Proceedings of the National Academy of Sciences has published a survey, which says that genes may determine friendship. James Fowler, the author of the whole article, who made this research along with other members, said that the researchers took six types of genes from National Longitudinal Study of Adolescent Health and Framingham Heart Study to examine if there is any genetic similarity between friends.

The researchers said that they were amazed to see that as they proceeded their tests, few genotypes actually clustered together! Researchers found out that the carriers of one gene associated with alcoholism and gene linked with openness and metabolism tended to stick with each other, respectively. One gene, DRD2, has been associated with alcoholism and CYP2A6 has been associated with metabolism and openness. The researchers say that people who like to drink might make their friends when they drink at a pub and this behavior explains their genetic link.

Professor James Fowler of the University of California said that many times people get an instinct from inside if they are going to like someone or dislike someone and these instincts come from inside. James Fowler meant to say that these instincts might be determined by the genes. Hence, the researchers carried out the test to understand the genotypes to know more about it. James Fowler said that people are not only affected by the social “susceptibility” of their friends but also by their biological “susceptibility” as well.
