News - Rare Sesquizygotic Twinning

Twinning historic drawing by William Smellie (1697-1763)

Sesquizygotic twinning is a rare intermediate form of twinning, lying between mono-zygotic and dizygotic twinning, the twins can be maternally identical but chimerical for their paternal genome. This rare twinning event has been recently identified in a amniocentesis genotyping study^[1] that showed twins that were maternally identical, but chimerically shared 78% of their paternal genome.
