**In a family twist straight out of a sci-fi plot, two sets of identical twins have given birth to baby boys with such striking genetic similarities that they are essentially genetic brothers—despite being cousins.**

**Yep, it sounds like something from a mind-bending riddle, but it’s entirely real.**

**Meet Brittany and Briana Salyers, an identical twin duo who are already famous for their unusual marital situation—they’re married to twin brothers, Josh and Jeremy.**

**After their joint wedding in August 2018, each couple welcomed their first child, and in an extraordinary twist of fate, both couples had baby boys.**

**The first set of twins, Brittany and Josh, became parents to Jett in early 2021.**

**A few months later, Briana and Jeremy welcomed their son, Jax, into the world in April 2021.**

**Talk about making a statement—these babies are more than just cousins; they’re practically genetic siblings.**

**To add a layer of confusion, Jett and Jax have names that are so similar you’d think they were destined to be mistaken for each other.**

**As the boys have grown, their differences have become more apparent—one sports darker hair, which makes it a bit easier to tell them apart.**

**The mothers cleared up the mystery on Instagram, posting a photo of their sons with the caption: “Jett and Jax: Cousins, Genetic Brothers, and Quaternary Twins!”**

**So, what on earth are “quaternary twins”?**

**The term describes offspring from two sets of identical twins, creating a unique family structure where cousins are genetically as close as siblings.**

**Despite this explanation, many are scratching their heads and asking questions.**

**“Does this mean they have identical DNA?” one puzzled follower queried.**

**Another chimed in with: “How are they genetic brothers exactly?”**

**A third clarified: “Their mothers and fathers are identical twins. Both sets of parents had kids. Same exact DNA created both. Make sense?”**

**The intricacies of this family tree might still seem confusing, so let’s break it down further.**

**Identical twins, like Brittany and Briana, share the same DNA. Their husbands, Josh and Jeremy, do as well.**

**When these identical twins have children, the genetic overlap is so significant that their offspring can appear as close as siblings.**

**In essence, Jett and Jax, while legally cousins, have enough shared DNA to be considered genetic brothers.**

**This phenomenon isn’t just a curious quirk; it’s a rare instance of genetic overlap that sheds light on the complexities of familial relationships.**

**To get a better grasp, let’s rewind to how this all started.**

**Brittany and Briana Salyers, along with their husbands Josh and Jeremy, became a media sensation when they participated in a “Twice Upon a Time” joint wedding at the Twins Days Festival in Twinsburg, Ohio.**

**The festival, a haven for twin enthusiasts, hosted the unique ceremony in August 2018, celebrating their double-dose of identical joy.**

**During their TLC documentary, *Our Twinsane Wedding*, the couples expressed their desire to synchronize their family lives.**
**Jeremy revealed, “We want to have twins, and we want them to be born on the same day… We’ll be raising our families together as well.”**

**Their commitment to having children around the same time paid off spectacularly, resulting in the birth of Jett and Jax.**

**This genetic overlap between cousins was something the couples eagerly anticipated, further enhancing their shared experiences.**

**Despite their unorthodox family setup, the couples have clarified there’s no partner swapping between the siblings—just a unique, tightly-knit family unit.**
**The Salyers and the brothers have become a real-life example of how intricate and fascinating family genetics can be.**

**The science behind their unique family structure might be complex, but it’s clear their lives are anything but ordinary.**

**As Jett and Jax grow up, their genetic bond will likely continue to intrigue and fascinate those who follow their story.**

**The family’s extraordinary genetic makeup provides a fascinating glimpse into the intricacies of human biology and familial connections.**

**From identical twins marrying identical twins to raising genetically linked cousins, this family’s story is a testament to the surprises life can offer.**

**As they navigate their shared journey, Jett and Jax will embody one of the most unusual genetic scenarios seen in modern times.**

**The fascination with their story underscores a broader curiosity about how family dynamics can be influenced by genetics.**

**Their unique bond is not just a family anecdote but a real-world example of how genetics can create unexpected familial relationships.**

**While their situation might be rare, it highlights the incredible ways in which genetics and family structures intersect.**
