The couples had met in 2017 at a festival for twins. Identical twin sisters Brittany and Briana Deane got married to identical twin brothers Josh and Jeremy Salyers. And now, while one of the couples recently welcomed their baby boy, the other set is expecting their first child.

What happens if two sets of twins have a baby?

Our children will not only be cousins, but full genetic siblings and quaternary multiples! Cant wait to meet them and for them to meet each other! Identical twins share very similar DNA. This means that the babies will legally be cousins, but genetically, theyll be closer to siblings.

What is the IQ of identical twins?

By then they had measured the IQ of 48 pairs of monozygotic, or identical, twins, raised apart (MZA) and 40 pairs of such twins raised together (MZT). The MZA twins were 69% similar in IQ, compared with 88% for MZT twins, both far greater resemblances than for any other pairs of individuals, even siblings.
