Time to get scientific - it turns out opposites DON'T attract, after all...
A new study has found that married couples are more likely to have similar DNA.
Research by the University of Colorado Boulder has uncovered that we are most likely to fall for people who are similar to us genetically.
In a study of 825 American couples - and 1.7million DNA sequence variations - researchers noticed that there were fewer genetic differences between married couples than between two people picked at random.
Like, what?! So perhaps there's not so much truth in the old addage 'opposites attract' after all...
Although if you think about it, is it that surprising? You're arguably more likely to be attracted to someone who you have common interests and outlooks with - and so perhaps it's not that mind-blowing that it might extend to your DNA pattern, too.
Benjamin Domingue, part of the research team, explained it in greater depth to Reuters, revealing: "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".
