When it comes to love, people will do anything to find the right partner. Whether it be dating sites, going to bars on the weekends, or blind dates people are on the constant search find true love. Turns out, no matter how hard we try to find our "perfect man/woman", our genes already have it all figured out. People may think they have a "type" such as tall, dark, and handsome, but odds are that if you're Irish theres a small chance that is who you end up with.
Researchers at the University of California- Berkeley, Harvard University, University of California- San Francisco, and Tel Aviv University have studied how couples pair up in certain communities such as Mexico, Puerto Rico, and the U.S. Results show that both males and females tend to attract mates who are in fact similar to them. This is a concept known as assortative mating and it is a phenomenon that can be seen amongst all races, ages, and body types.
In a 2009 study researchers found that out of 90 married couples and 152 random pairs, the 90 married couples were found with more diverse MHCs. MCHs are a genetic region that plays a role in immune response and reproductive success. The scientists believed this to be the result of an evolutionary strategy to increase reproductive success.
Also, another study was conducted at University of Colorado- Boulder where researchers studied the genetic profiles of 825 white couples. The study examined the single-nucleotide polymorphisms which are the parts of the DNA that show how humans differ from one another. The researchers found that married individuals are more likely to be genetically similar than two random individuals from the same population.
It is difficult to believe that people really have much less control over who they date or marry than they think. People learn to rely too much on their brains when in fact they should just follow their heart and if their lucky their genes may help them find their perfect match.
