In order to test the hypothesis that somatic mosaicism involving C-band polymorphism of human chromosomes 1, 9, 16 may arise from mitotic crossing over, peripheral blood lymphocytes from normal males were treated with mitomycin C, which is known to induce somatic crossing over in lower eukaryotes.

โฆ Synopsis
We present a classification for secondary constriction (qh) regions with C-banding technique in chromosomes 1, 9, and 16 by means of comparing them to the short arm of chromosome 16. It is simple and convenient and can be used routinely. It can be incorporated into the modified Paris nomenclature system.

Thirty-two pairs of Caucasoid twins, 16 monozygotic (MZ) and 16 dizygotic (DZ) of the same sex, were studied in relation to the C-bands of chromosomes 1, 9, and 16. Concordance was not absolute among MZ, the best evaluation of the degree of genetic determination for these traits being 0.40 for chrom
The secondary constriction (SC) regions of human chromosomes A1, C9, and E16 were preferentially stained with Giemsa when the mitotic cells in a hypotonic solution were heated in a water bath before fixation. The staining intensity of these regions increased from E16 through A1 to C9. The SC region
