[Comparative study of methods for the quantitative assessment of the C-segment size of human chromosomes].
The possibilities of comparison and reproducibility of results of estimation of the absolute dimensions of chromosomal C-segments measured by different methods have been studied. The data obtained indicate good comparability of the results obtained by all the methods in a definite range of chromosome condensation. All the methods demonstrated satisfactory reproducibility of the results on chromosomes 1 and 9. The errors of the quantitative estimation of chromosome 16 in the coupled cultures is discussed in view of the artefact nature of C-segment size variability.
