Like Family, Many Friends Share the Same Genes


GOODMORNING Bloggers!
well i saw this article and immediately thought to myself, " makes sense my best friend who Ive know since 2ND grade is basically like my sister" so hopefully this sweet and simple article keeps you interested and entertained.

Many of us have those friends we can count on for everything -- the ones we feel really connected to.

It turns out, that much like we are with family, we also may be "connected" to our friends through our genes, according to a study from the University of California, San Diego.

Dr. James Fowler, professor in the School of Medicine and the Division of Social Sciences at the University of California, San Diego, and his colleagues studied more than 3,000 pairs of friends. Fowler and his team compared the similarities of six genes thought to be associated with social behavior. What they found was that many friends share the same type of genes.

The findings will be published in the early edition of the journal of the Proceedings of the National Academy of Sciences later this week.

"There may be a partially genetic basis for friendship," Fowler told AOL Health. "This is the first step towards understanding the biology of 'chemistry' -- that feeling you have about a person that you will like or dislike. We may choose our friends not just because of the social features we consciously notice about them, but because of the biological features we unconsciously notice."

Researchers found that many friends share the DRD2 gene, which is associated with an outgoing personality and is also linked to alcoholism.

Another gene, the CYP2A6 gene, which is associated with "openness" was less likely to be shared by friends, however. These people were more likely to look for friends who had slightly different personalities than their own.

Dr. Irene Levine, a psychologist and professor of psychiatry at the New York University School of Medicine, and author of The Friendship Blog and "Best Friends Forever: Surviving a Breakup with Your Best Friend," surveyed more than 1,500 women online to find out what attracted them to their best friend. "Women often used the same term, 'we clicked,' to describe the indescribable," Levine told AOL Health.

"The choice of friends (or lovers) is influenced, of course, by personality -- which is shaped by a complex mix of genes and environment," she explains. "Two old adages ... seem to apply: 'Opposites attract' and 'Birds of a feather flock together.' Sometimes people are attracted by differences; other times, they are attracted by similarities that make them feel comfortable."

Dr. Margaret Gibbs, professor emeritus of psychology at Fairleigh Dickinson University in New Jersey, agreed. "I think it's interesting that the study found both sides of the popular aphorisms: 'Birds of a feather flock together' and 'Opposites attract,'" she told AOL Health. "I think those same principles work in our choices of friends. We feel comfortable with the familiar, but also seek balance and variety."

"Perhaps people vary as to whether they are more inclined to pick the familiar over the different, and, who knows, that inclination could be genetic, too," adds Gibbs.
