title: [Discriminant functions for the diagnosis of twin zygosity from questionnaire data].
abstract: Discriminant and successive analyses of formalized data obtained on the basis of questionnaire response were carried out in 232 twin samples of the same sex to estimate a degree of their similarity. The data were taken from the Twin Register of the Institute of Medical Genetics and treated concerning three characters: 1) subjective estimation of the similarity; 2) distinguishing twins by other people; 3) the use of special marks. The variants of discriminantal functions allowing to divide twin zygosity into monozygotic and dizygotic groups have been obtained, the classification error being 4 to 6%. The tables with diagnostic coefficients for twin zygosity diagnosis constructed on the basis of successive analysis are presented.
