Two recently born babies are both cousins and genetic brothers due to an extremely unlikely scenario. Brittany and Briana are identical twins who married identical twins Josh and Jeremy Salyers and then gave birth to babies within months of one another.

Brittany and Briana shared their story on Instagram, and soon their fans were trying to figure out the unique connection between the babies.

They uploaded an Instagram post of their adorable sons Jett and Jax and said they are; “Cousins, genetic brothers, and quaternary twins.”

Many people took to the comments section, confused at how this was possible. As one wrote: “Their mothers and fathers are identical twins. Both sets of parents then had kids. Same exact DNA created both.”

Then a second wrote: “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!”

They had a joint wedding on August 5, 2018, live in the same home in Virginia, US (United States), and are now expanding their families together.

Previously, the pair broke the pregnancy news on their shared Instagram page and said they wanted to fall pregnant at the same time writing: “Guess what!!?? BOTH couples are pregnant!”

The post continued: “We are thrilled and grateful to experience overlapping pregnancies and to share this news with you all!”

“Our children will not only be cousins but full genetic siblings and quaternary multiples! Can’t wait to meet them and for them to meet each other!”
