Karyotype array of the near-triploid cervical carcinoma SiHa. The SiHa array with the attached table, prepared as for Figure 6, shows that the total chromosome number is quasi-clonal at 66±4. The copy numbers of 60-100% of the chromosomes were clonal forming parallel lines in the array. The non-clonal chromosomes included intact chromosomes with near-clonal copy numbers and non-clonal marker chromosomes, which were found in six of 20 cells. Comparison of the karyotype array of SiHa with those of the near-diploid carcinomas C-4II and C-33A (Figures 6 and 7) shows at a glance that all three carcinomas have distinct, individual karyotypes.
