Research reveals that mates have a remarkable number of the same genes.
The study, which gives new weight to the saying ‘birds of a feather flock together’, found that pals share significantly more DNA than strangers.
Geneticists discovered that unrelated friends have a 1 per cent of genes that match – about the same as fourth cousins, who share great-great-great grandparents.
‘One per cent may not sound like much to the layperson, but to geneticists it is a significant number,’ said Professor Nicholas Christakis, of the Human Nature Lab at Yale University.
It means that scientists are even able to make a calculated guess as to which people are likely to become friends just by testing their DNA.
Co-author Professor James Fowler, a medical geneticist at the University of California at San Diego, said: ‘Looking across the whole genome, we find that, on average, we are genetically similar to our friends.
‘We have more DNA in common with the people we pick as friends than we do with strangers in the same population.’
It is thought the explanation is rooted in human evolution.
Early humans may have formed groups that were genetically suited to the same environments, or had similar likes and dislikes.

This is very interesting... When you talk to and get to know and love people online, is this somehow also directed by DNA? Maybe DNA has more functions than we realize. I know for a fact JR and I are not related in any way, but it would be interesting to compare DNA
