Sisters Explain How Their Sons Are Brothers, Cousins And Twins

Twins Brianna and Brittany Sayler have baffled their followers after revealing that their individual sons are cousins, brothers, and twins all at once.

Brianna and Brittany have really embraced their twinship over the years, and even married identical brothers Jeremy and Josh in a joint ceremony.

The sisters had previously starred in TLC show Extreme Sisters - a programme about sets of sisters who share a unique, rather intense bond with one another.

You can take a look at their appearance on the show here:

Within three months of each other, both Brittany and Briana welcomed baby boys Jax and Jett, and thanks to their DNA, the tots are connected in more ways than one.

In a post to their joint Instagram page, the twin sisters shared a photo of their sons, adding the caption: "Jett and Jax: Cousins, Genetic Brothers, and Quaternary Twins! 🌞🌞"

It sounds pretty wild, but when two pairs of identical twins marry each other, their children - who would typically be considered first cousins - are also technically genetic siblings.

Thanks to their parents, Jax and Jett's DNA would look exactly like that of full genetic siblings.

After some confusion among followers, some took it upon themselves to explain how Jett and Jax are as connected as they are.

One wrote: "Their mothers and fathers are identical twins. Both sets of parents then had kids. Same exact DNA created both. Make sense?"

Another added: "Identical twins share the same DNA and both sets of parents are identical. If this family took an ancestry DNA Test it would show these babies as siblings, not cousins!"

Other followers couldn't get over how much the quaternary twins looked like one another.

"That’s so crazy! They’re almost identical. 😮" wrote one.

"Wow. They look like twins" added another.

"I [thought] it was the same baby at first🥲" a third commented.

This is honestly blowing our minds.
