Аннотация
The position of chromosomes No. 9 and of the Y chromosomes in interphase nuclei was observed by means of the Giemsa-11 staining and the quinacrine mustard fluorescence staining respectively. 3 fibroblast cultures from normal female persons and 1 culture from a person with the karyotype 47/XYY were used. The distance between the two homologous chromosomes was compared with the theoretical expected distance between two points which are randomly positioned in a circular area. The distance between the chromosomes No. 9 as well as between the two Y chromosomes is significantly smaller than expected with a random position. This tendency for a somatic association is stronger in the case of the two Y chromosomes than in the two chromosomes No. 9.
