Semi-identical twins are double delight for geneticists

An Australian brother and sister born in 2014 share the same DNA on their mother's side, but only a few of their parents – the result of two sperm fertilizing an ovum – according to a report from yesterday The new English Journal of Medicine. The sesquizigotic brothers are only the second known case of semi-identical twins, and the first to be discovered in the uterus.

Is there a risk to health? Its "extraordinarily rare" genetics makes twins susceptible to an unusual form of cancer, but doctors will be aware of the pair.
