Twin sisters Brittany and Briana Salyers, who are married to twin brothers Josh and Jeremy, have welcomed baby boys who are not only cousins but also genetic brothers. The rare phenomenon, called quaternary twins, happens when children of identical twin couples share more genes than regular cousins. Brittany and Briana explained their sons, Jett and Jax, are cousins but share DNA as though they were brothers due to their parents being identical twins.
The families became viral sensations after their story caught attention, with fans amazed by their identical lives. The couples married in a joint ceremony in 2018 and had previously expressed their desire to get pregnant at the same time. Their unique family dynamic has left many puzzled, with some even asking whether Jett and Jax have identical DNA, prompting the parents to explain the concept of quaternary twins on social media.
Quaternary multiples are extremely rare, making this family tree one of the most unusual. The twins’ journey has been shared through documentaries like TLC’s Our Twinsane Wedding, where they expressed their goal of raising their children together. While it’s difficult for people to wrap their heads around the genetic complexities, DNA tests would likely show Jett and Jax as siblings, not cousins.
The couples continue to share their unique lives online, often confusing and fascinating followers with their mirrored experiences. Despite their unorthodox situation, they maintain clear boundaries, explaining that there is no partner swapping between the twin couples.
