A MUM has revealed that her daughter has a genetic sister, who does not share the same mum or dad. Venessa Sealby is a twin, and she and her sister Kerissa married a set of twins, named Lucas and Jacob. 3 Venessa and Lucas have a baby called Adrian Credit: tiktok/@todayshow 3 Kerissa and Jacob share a baby called Sophie Credit: tiktok/@todayshow 3 The two babies are biological siblings Credit: tiktok/@todayshow Venessa and Lucas share a five month old daughter named Adrian , while Kerissa and Jacob share 19-month-old Sophie.
Obviously, Adrian and Sophie are cousins, however, they are also genetically siblings, known as quaternary twins. Quaternary twins occur when two sets of twins have children with each other. The two babies share DNA, in the same way that siblings do.
Speaking to The Today Show, the family said: "For us, it's a really cool experience. "They're going to be like twins as they will grow up together". The two couples live in neighbouring houses in Oregon, USA , and are constantly popping over to each other's homes.
They hope to get pregnant at the same time again for baby number two, so that they can raise their next children as if they are twins.
