Bold, number of copies of chromosome (n) observed out of 10 metaphases. Italics, total number of copies of chromosome in 10 metaphases; this is the number used to determine the chromosome content ratio.

*There are no full copies of chromosomes 4 and 11 in any of the cells. However, portions of chromosome 4 and 11 are represented in der chromosomes (see Table 2).

^†In some metaphases, chromosome 22 is indistinguishable from marker chromosomes by SKY. Detailed examination with FISH showed a DB-A2/DB-P ratio of 1.02 (240/236 signals for chromosome 22 in 60 cells). Their value is used as chromosome content ratio.
