To explain their physical similarity, science highlights their genetic heritage and gives a rational explanation: the twins gave birth to “quaternary twins”. In other words, these children are cousins but have sibling DNA. This is a rare case of genetics.

Perfectly identical, Brittany and Briana are identical twins (this is what we call in medicine “monozygotic twins”). Originally from Virginia, in the United States, since their early childhood, their mimicry has always been blatant. Inseparable and perfectly synchronized, they shared everything together, dressed the same and had the same interests. Their bond was so powerful and close that the twins even ended up marrying two identical twin brothers in 2018! Suffice to say that this type of union is extremely rare. Stranger still, the two sisters became pregnant almost at the same time.
In January 2021, Briana and Jeremy became the happy parents of little Jax. They published the news on the Instagram account that the two couples have in common. “ I am so proud of my beautiful wife, Briana (…). She was so strong and courageous. She did an incredible job », wrote Jeremy to caption his publication. Three months later, in April, it was the turn of Britanny and Josh to welcome their son named Jett. They also shared the news on the social network: “ I’m so proud of my wonderful wife and really excited to be Jett’s dad! », writes the young dad.
Not only did the quartet have boys, but the parents mutually decided to choose names starting with the letter “J”. But, the similarity doesn’t end there. Everyone noticed that the two babies looked strangely similar. In truth, there is nothing very surprising about that. Thanks to their very close genetic heritage, these children are not only cousins, they also share fraternal DNA. Scientifically speaking, this rare phenomenon even has a name: quaternary twins.

After posting a photo of their sons side by side on Instagram, the Salyers couple wrote: “ Cousins, genetic brothers and twins! “. A nice mix, right?
Cousins who look exactly alike!

That is, although they are cousins in real life, after inheriting the parental genetic mix, in terms of DNA, they can easily be considered brothers. Since their parents are identical twins, the little ones can be described as “quaternary twins” since they are genetically related to Brittany, Briana, Josh and Jeremy. Yes, it can easily make you dizzy! Moreover, Internet users did not fail to express their confusion. Below the post, the comments seem quite confused and troubled. People try, as best they can, to reconstruct the relationship between these two babies, as well as that of their parents.

This post quickly became the scene of a large debate around genetics and twins. “ It’s not that complicated to understand: since the mothers and fathers are identical twins, it’s normal that the children look so similar! », writes a follower. “ Both sets of parents had children. The latter inherited the same DNA from both groups. If this family did a DNA ancestry test, it would show that these babies are siblings, not cousins! said another user. Other people remained perplexed, saying that the connection between the two boys was rather curious and strange. “I had never heard of it before…” confesses one Internet user. However, many users congratulated the happy parents and applauded the new family. “ Your children are magnificent. I love their names! », We can read in a comment.
