Their babies are cousins, but genetically they are brothers
Identical twins Briana and Brittany, 35, married identical twins Josh and Jeremy Salyers, 37, and now they’re introducing the world to their babies, who are so genetically similar that the cousins are more like brothers.
“You’ve heard the term Irish twins and you’ve heard identical twins and fraternal twins,” Briana Salyers told
“But we have quaternary twins.”
The Salyers are parents to Jett, who turned 1 in January, and Jax, who will turn 1 in April, and the cousins share more than the same first іпіtіаɩ. Their ᴜпіqᴜe situation makes them genetic brothers.
“They were born to identical twin parents less than nine months apart,” Brittany Salyers explained.
“Twins married to twins who both have babies at the same time.”
Since identical twins share the same DNA, the children of two pairs of identical twins are legally cousins, but genetically more similar to siblings.
The sisters shared they had both discussed the possibility of quaternary twins.
“We were hoping that we would have overlapping pregnancies so that this would happen. We thought it would be really cool,” Briana said. “There’s only 300 quaternary marriages known in the history of the world.”
Both 2 babies are the same as twins .
