title: [The value of the newest results of blood group research in the study of hereditary diseases].
abstract: Authors discuss the recent development of chromosome-research, particularly problems concerning gene-localization and the role of blood group research in it. Blood-group Xg and its significance for the construction of the genetic map of human X chromosome and delineation of the pattern of inheritance of the X-linked disorders are described. Results of observations carried out on 178 pairs of twins of similar sexes in order to determine zygozity are shortly reviewed. The DZ : MZ ratio have been found 45 : 55.
