[Individuality of human chromosome polymorphism revealed by Q-staining].
The G-polymorphism of metaphase chromosomes of peripheral human lymphocytes and its inheritance in 32 families (268 persons) and 315 unrelated persons after G-staining has been studied. The site of Q-heterochromatine, its size and the length of secondary constrictions were accepted as morphological signs of Q-polymorphic variants of chromosomes. All the three chromosome signs are shown to be inherited according to codominant type and are characteristic features of each separate chromosome. No identical patterns of Q-polymorphic chromosome variants are found among all the persons studied, except the monozygotic twins. According to the data obtained, the question of individualization of each chromosome in the karyotype (3, 4, 13--15, 21, 22) and of each personal individuality in relation to Q-polymorphism is discussed.
