The morphologic variations of C-band heterochromatin of chromosome 9 were studied in 600 Greek subjects referred for cytogenetic investigation. There was great variability in the location and length of the heterochromatic bands. The location and length of the heterochromatic band were equal in 177 individuals and unequal in 423. Twenty-five subjects (4%) carried a pericentric inversion on one of the homologs, and 12 individuals (2%) had an extremely elongated C-band in one homolog 9. Our findings are compared with those reported in the literature, and the ethnic variation is discussed and evaluated.
对600名接受细胞遗传学检查的希腊受试者的9号染色体C带异染色质的形态变异进行了研究。异染色质带的位置和长度存在很大差异。177名个体的异染色质带位置和长度相等，423名个体的则不相等。25名受试者（4%）在其中一条同源染色体上携带了一个臂间倒位，12名个体（2%）的一条9号同源染色体上有一条极其细长的C带。我们将研究结果与文献报道的结果进行了比较，并对种族差异进行了讨论和评估。
