Spouses Often Share DNA, New Study Finds

According to a new study, spouses are more likely to share DNA with each other than other people.

Research out of the University of Colorado's Institute of Behavioral Science took a group of both married couples and randomly selected participants, and found the couples had more similarities in their genetic makeups.

Benjamin Domingue, the lead researcher on the study, notes in some respects, this isn't too surprising.

"For example, people clearly care about height in picking partners. To the extent that tall people marry other tall people, that is going to result in genetic similarity among spouses. But it is difficult to know whether height or genes is driving this decision," Domingue told Reuters.
