The Odd Commonality of Spousal DNA

A new study from the University of Colorado-Boulder has shown that spouses tend to have DNA that is more similar to one another than to a different randomly selected person.

The researchers utilized 825 couples. Each participant’s genome was compared to their spouse and then to two other people who were randomly selected. Couples were more likely to be similar to one another than to the people with whom they were randomly paired.

The researchers have noted that based on this study, this “genetic assortative mating” explains about 10% of educational assortative mating. While genetics appear to be a factor in mate choice, it is a small one.

About Heretic

I design video games for a living, write fiction, political theory and poetry for personal amusement, and train regularly in Western European 16th century swordwork. On frequent occasion I have been known to hunt for and explore abandoned graveyards, train tunnels and other interesting places wherever I may find them, but there is absolutely no truth to the rumor that I am preparing to set off a zombie apocalypse. Nothing that will stand up in court, at least. I use paranthesis with distressing frequency, have a deep passion for history, anthropology and sociological theory, and really, really, really hate mayonnaise. But I wash my hands after the writing. Promise.
