title: [Spatial arrangement of chromosomes in somatic cell nuclei. IV. Homologous chromosomes in guinea pigs and domestic pigs].
abstract: Space location of chromosomes in metaphasic cells was investigated using brains of 30 Cavia cobaya and 30 Sus scrofa, in norm and under X-ray treatment (500 r) and dipin action. Conjugation of homologous chromosomes under normal conditions was determined, with a high rate reliability, to be equal to the 0.99 level of measuring, within the limits of the elaborated mathematical model. High rate of translocations of homologous chromosomes were discovered in animals subjected to the above mutagen treatments. The architecture of cell nuclei is discussed.
