Considering the development of the twin method the Authors deem it necessary to review the various systems of analysis presently used. They therefore design a method by which the twin material may be used even when zygosity is unknown. The Authors give this method the name of Azygotic Twin Test (T.G.A.), explain it theoretically and also give a practical example of analysis.
The Authors plan to make - new studies on the subject, in order to show further possible developments of this method.
