The Reason Lots Of Married Couples Look Alike Will Kind Of Gross You Out

In a similar fashion to how pet owners tend to look like the animals theyhave, married couples will often looklike theyre more brother and sister than they are husband and wife.

Ever wonder why that is?

Well, it seems that thesimilarities in appearance of those who are married isnt because of chance. Instead, its literally because they could havesimilar genes to begin with, according to EurekAlert.

A recent study published inPLOS Geneticsfoundthat, in older generations, people tended to marry others who shared some similar type of ancestry with them.

According to the study authors, this weird tendency to drift toward people with a comparable family tree can greatly impact the genetics of people within a certainarea.

Until recent years, most people looking for love tended only to pick someone from within their surrounding areas likely due to accessibility and proximity which often contained people of a similar genetic history.

As this pattern repeated over long periods of time, those married couples who shared a similarancestry then had kids, and as that cycle continued through generations, scientists realized it may have significantly impactedany genetic studies conducted in that area.

During theirvery first examination ofthe patterns of married couples sharing similar genes in specific areas across the United States, researchers focused on partners from three different generations of people from Framingham, Massachusetts.

These individuals all took part in the Framingham Heart Study, a heart health study that beganin 1948.

After genetically determining the ancestry of grand total of 879 married couples, researchersfound those ofNorthern European, Southern European and Ashkenazi descent were most likelyto drift toward spouses who shared the same background as them.

This is still so odd, but hey, to each his own. Some people dont look to branch too far outside their own box.

As time went on, researchers noticed the following generations tended to drift away from this pattern, with people becoming to choosea spouse who shared a similarbackground. And any genetic structures resulting from these mating patterns also deteriorated.

Its unknown if these findings carry over todifferent communities, but its something worth researchingmore in the future.

Researchers concluded that these genetic similarities within the same area could result in some false positives when identifying specific genesand their connections to diseases present in certain areas.

It may also alter how adisease could be passed on genetically from generation to generation.

The moral of this story isthat people should stay away from anyone with the same ancestry. Youre confusing researchers and, frankly, just grossing people out.

Change is good, I promise.
