Researchers observed that the genes affecting sense of smell were especially likely to be similar in friends
Singapore: A latest study conducted by researchers from the University of California, San Diego has suggested that friends share DNA similarities.
The study suggest that you may be more similar to your friends than you think. It explains how the DNA code tends to be more alike between friends than between strangers. This, researchers pointed out is beyond the effect of shared ethnicity.
One of the lead researcher Mr James Fowler from the University of California said that this can be important for theories about human evolution.
Mr Fowler, along with Yale researcher Mr Nicholas Christakis presented their findings in a paper that was released by the Proceedings of the National Academy of Sciences.
The research included 1,932 participants in a long-running health study in Framingham, Massachusetts. A report explained that the researchers knew who was close friends with whom from the 1970s to the early 2000s because of information gathered for the study.
