I Love Your Genes; We Should Get Married!

couple in love

Looking for love? Look for yourself. A new study reveals that husbands and wives have similar DNA.

Killer smile? Check. Good job? Yep. Table manners? Not bad. Funny? Definitely. Nice to the waitstaff? Incredibly.


Turns out, if you're looking for The One, it may be time to re-work your list of dealbreakers and start paying closer attention to your date's genetic profile. Forget "opposites attract" — "birds of a feather flock together" is actually a much better rule for finding your perfect match, says science.

New research in the journal Proceedings of the National Academy of Sciences revealed that people tend to pick spouses whose DNA is just like theirs. After studying 825 non-Hispanic white couples, mostly born in the 1930s, (which, yes, is certainly a limited pool) they found that spouses were more similar to each other than they were to random individuals. While having other things in common, such as education, have a larger influence, this discovery proves that love isn't genetically random. 

"It's well known that people marry folks who are like them," said Benjamin Domingue, the study leader and research associate at University of Colorado Boulder's Institute of Behavioral Science, "But there's been a question about whether we mate at random with respect to genetics."

So how are so many people finding their genetic matches? It could be that people tend to marry someone who lives in the same area or someone of the same ethnicity.

Domingue also theorizes it could be as simple as picking out someone of similar height. Another possibility is people with similar DNA have the same hobbies and interests. Maybe there is more to you and your guy's bond over Arcade Fire — your genetic similarities.

So if things aren't going well, we now give you permission to use, "It's not you, it's your DNA."
