Twins Thought To Be Identical Turn Out To Have Different Fathers

There really is no way of telling how things are going to turn out. A pregnancy can turn out a lot of different ways, and that goes double when someone's having twins.

They can be identical, fraternal and in rare cases, conjoined. That happens once about every 200,000 births, but there's one thing that's even rarer.

When a mother in Vietnam had her twin sons, she couldn't help but notice how different they looked. While it's definitely true that twins aren't always identical, these two didn't even seem related.

She and her husband wondered if the hospital had given them the wrong baby, but DNA testing proved that wasn't what happened.

Instead, the truth was a lot more unexpected. And you can watch the full video to find out just how it happened.

As the twins grew into toddlers, the family discovered one of them had thin, straight hair while the other had thick, wavy hair. Baffled, the parents submitted them for DNA testing.

They found out that even though the twins shared the same womb, they had different fathers. The testing was done by the Vietnam Genetic Association, who said the results were 100% accurate. This was Vietnam's first case of bi-paternal twins.

This happens so rarely that there are less than 10 known cases of it in the world, but it's hard to tell how many are going unreported.

And the reason it's so rare is because so much has to come together for it to happen. A woman has to produce two eggs in a short time frame and two different men have to have sex with her within a few days of each other.

Of course, even that doesn't guarantee this will happen, but it sure did in this case.
