They’re being called semi-identical twins and a new study in the New England Journal of Medicine suggests that such twins are extraordinarily rare. The only other reported case was uncovered in 2007.

LONDON - Doctors in Australia say they have identified a second case of twins apparently created from one egg and two sperm, a boy-girl combination in whom the mother’s DNA is identical in both babies but the father’s DNA varies in each twin.“This is confirming there is this third type of twinning where it’s not fraternal and it’s not identical.

In the case of the Australian twins, who live in Brisbane and are now 4-and-a-half years old, the mother’s egg was fertilized with one sperm carrying an X chromosome and one with a Y. Because an ultrasound taken early in the pregnancy showed that both fetuses shared the same placenta, doctors assumed the fetuses were identical twins.

The twin boy and girl were found to have 100% of their mother’s DNA in common, but were only 78% identical in the paternal DNA they carry.
