The power of twin designs arises from the fact that twins may be either identical (monozygotic (MZ), i.e. developing from a single fertilized egg and therefore sharing all of their polymorphic alleles) or fraternal (dizygotic (DZ), i.e. developing from two fertilized eggs and therefore sharing on average 50% of their alleles, the same level of genetic similarity found in non-twin siblings).
Twin studies that investigated the development of schizophrenia found that identical twins have a higher concordance rate for schizophrenia than non-identical twins. [18] [19] [20] However, none of them found a 100% concordance rate from identical twins. Identical twins have exact genes.
