Study finds genetic similarities among friends not biologically related

WASHINGTON: Friends who are not biologically related still tend to resemble each other when it comes to genetics, revealed a US study published Monday that proved that "friends are the family you choose."

"Looking across the whole genome, we find that, on average, we are genetically similar to our friends," lead author James Fowler, professor of the University of California, San Diego, said. "We have more DNA in common with the people we pick as friends than we do with strangers in the same population."
