Unequal rate of monozygotic and like-sex dizygotic twin birth: evidence from the Minnesota Twin Family Study.

Behavior genetics - 1 Jul 1995

Hur Y M, McGue M, Iacono W G

Abstract excerpt

It is generally believed that in Caucasian populations the rate of monozygotic (MZ) twinning is approximately equal to the rate of like-sex dizygotic (DZ) twinning so that representative samples of like-sex twins should contain approximately equal numbers of MZ and DZ twins. Recent evidence suggests, however, that the rate of DZ twinning in Caucasian populations has declined over the past 50 years so that there...
