Genetic Match? People Marry Those With Similar DNA
New research supports the idea that people tend to pick spouses in which their genetic profile is similar to their own. Based on the journal Proceedings of the National Academy of Sciences, mating isn't truly genetically random. Benjamin Domingue from the University of Colorado, analyzed genetic information from 825 non-Hispanic white american and found that married people have more similar DNA segments than random pairs of people. It was found that people tend to marry others who are similar to them in education, social class, race and body weight; this is called assortative effect. The assortative effect based on education was three times stronger than sorting based on genes.
Further research from the LATimes compared 1.7 million single nucleotide polymorphisms and also found that married couples were more genetically similar than random pairs. Even though similarities in genes were found in married couples, it was only one third the magnitude compared to educational similarities found between couples.
