1957 Ann. N.Y. Acad. Sci. 64 759 Because the twins were believed to be probable monozygotics, excess skin was taken from the less extensively burned twin and cross-transplanted to her sister.

1988 Daily Tel. 7 June 17/8 One of the commonest instances of telepathy between monozygotics is the transferring of unhappiness, regardless of distance.

2000 Pediatrics 105 800 When only the youngest individuals in each group were considered, 100% (7/7) of the monozygotics and 50% (5/10) of the dizygotics demonstrated this trait.
