A study was carried out on C-banded chromosomes 1, 9, 16, Y from an unselected population and from 30 normal families. We found: a) great variability in length and position of the C-bands; b) somatic mosaicism involving C-bands; c) variants in children that were not present in parental patterns. The possible role of crossing-over in generating the last two phenomena is discussed.
对来自未经过挑选的人群以及30个正常家庭的1号、9号、16号C带染色体和Y染色体进行了一项研究。我们发现：a）C带的长度和位置存在很大变异性；b）涉及C带的体细胞镶嵌现象；c）子代中出现的变异在亲代模式中不存在。本文讨论了交换在产生后两种现象中可能发挥的作用。
