13] Several studies of twins suggest that NIDDM is highly concordant among monozygous and less concordant among dizygous twins, indicating that genetic factors play a major role in the etiology of NIDDM.
True dizygous (fraternal) twins would still reflect inheritance of their parents' genes but would not be matched across most loci, let alone be matched at these particular 16 loci simultaneously.
Two studies comparing monozygous and dizygous twins may be cited.
However, in such cases the risks could not be quantified because the database did not differentiate between monozygous and dizygous twin pairs.
