Molecular analysis of polymorphic markers can be used for �DNA fingerprinting� to determine the zygosity of twins. Monozygotic (identical) twins will inherit the same alleles from their parents for all of the markers tested, whereas dizygotic twins are likely to inherit different alleles (but they may inherit the same alleles by chance).
