However, an ultrasound at 14 weeks showed the twins were male and female, which is not possible for identical twins. Identical twins result when cells from a single egg fertilised by a single sperm divide into two, so identical twins are the same gender and share identical DNA.

Fraternal twins occur when each twin develops from a separate egg and the egg is fertilised by its own sperm. Dr Gabbett said if one egg is fertilised by two sperm it results in three sets of chromosomes, one from the mother and two from the father.
