What is the frequency of MZ and DZ twin births?
Birth rates for MZ twins are consistent among all races (about 4 per 1000); but the incidence of DZ twinning varies among races (8 per 1000, among Caucasians, 16 per 1000 among people of African descent, and 4 per 1000 among Asians). A genetic predisposition or inherited characteristic for DZ twinning exists in some families, but the consistency of MZ twinning among all populations suggests that identical twinning is a random occurrence that is not influenced by genes. Overall, about 1 in 80 births in Australia is a twin and of these about 30% are MZ.
