โฆ Synopsis
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. Evidence is presented which shows that mitomycin C is able to alter the heterochromatic pattern in human lymphocytes.

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 sy
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
