A quantitative analysis of the C-band polymorphism in chromosomes 1, 9, 16 and Y was made in 50 phenotypically normal individuals (25 males and 25 females). At an average level of the chromosome spiralization (the mean chromosome size is 2-7 micrometers) mean C-band lengths of chromosomes 1, 9, 16 and Y obtained in the course of the study are 1.09, 0.94, 0.82 and 0.80 micrometers, respectively. A comparative analysis of the mean C-band lengths in chromosomes 1, 9, 16 in the male and female groups has revealed no sex differences. The highest variability of the C-band size is found for chromosome 1 and the lowest--for chromosomes 16 and Y.
