Dna dating can genes help you pick a mate
Many studies have found that people tend to marry others who are similar to them in education, social class, race and even body weight. [I Don't: 5 Myths About Marriage] The question, according to study leader and University of Colorado research associate Benjamin Domingue, was whether these assortative mating differences are visible at the genetic level. They compared the similarity of the DNA of married couples with the similarity of random, non-coupled individuals.
The researcher analyzed genetic data from 825 non-Hispanic white Americans who participated in the U. The results, mirrored in a follow-up study with data from the long-running Framingham Heart Study, revealed that married people have more similar DNA segments than random pairs of people.
In general, the assortative effect of education was three times stronger than sorting based on genes, the study found.
The genetic effect on educational attainment played a small role: The research team found that no more than 10 percent of the variation in similarities in education had to do with similarities in genetics in a married pair.
The chance that it leads to wedding bells may depend, in part, on how similar his or her DNA is to yours.
New research finds that people tend to pick spouses whose genetic profile shares similarities with their own.
The effect is subtle (other similarities, such as similarity in education, have a larger influence), but it's important to understand that mating isn't truly genetically random, researchers report today (May 19) in the journal Proceedings of the National Academy of Sciences. social system might inadvertently sort people by genetics, for example, or contribute to schisms seen at the level of our very DNA.
They also examined the findings in the context of educational attainment, which is partly determined by intelligence.They found that after controlling for educational attainment, the genetic effect declined by 42 percent.
