[Red cell and serum polymorphisms to define main human races and to analyze mixed populations (author's transl)]

Using blood group serological chromosome markers one can distinguish by means of an integrating mathematical method of comparison at least five by and large pure, basic human races. These are: the Amerindios, the Caucasians, the Melanesians, The Negroids, and the Poly-Micronesians. A sixth race, the Neomongoloids, can be constructed on the basis of blood group characteristics from the mixed populations of the Far East. The Chinese, Japanese, and Ainu ethnic groups have large portions of this blood. It appears that the purest representatives of this sixth race are the Koreans. An analysis of blood group genes revealed signs of genetic drift among the Ainus, the Australian Aborigines, the Central and South American Indians (and, indirectly, also among the North American Indians) as well as among the Xhosas and Bantu. The gene impoverishment resulting from this drift may be a contributory factor to the problems of existence which these peoples have been experiencing in recent times.
