Thirty-five-year-old Virginian twin sisters, Briana and Brittany Deane, married twin brothers Josh and Jeremy Salyers, 37, back in 2018. Now, they are proud parents of boys who share the same genetics. Named Jax and Jet, the one-year-old sons of the twin couple were born three months apart and are cousins, but also brothers, because they share the same DNA.
Children born to separate parents but them sharing the same genetic makeup are labelled “quaternary twins.” The occurrence of quaternary twins is incredibly rare. They happen to exist when one set of identical twins has a child with another set of identical twins. While cousins still, these children genetically appear closer to siblings born to the same parents.
