title: MZ or DZ? only your blood grouping laboratory knows for sure.
abstract: Data from individual interviews, blood grouping analyses, and ratings of photographs of a large sample of adolescent twins were examined in order to assess the accuracy of zygosity determination by alternate methods. Although the accuracy of the twins themselves and of the raters was above chance, it was not sufficiently high to justify diagnosis by these methods rather than by blood grouping analyses.
