Six human dicentric translocations involving the presence of a suppressed centromere were studied: one case of t dic(9;22), one of t dic(13;18), one of t dic(14;15), and three of t dic(13;14). All exhibited chromatid separation at an acrocentric centromere and were demonstrated to have two regions o

A modified C-banding technique is described that produces C bands on human chromosomes after sequential Q and R banding and retains good chromosome morphology. Despite the considerable exposure to UV light during sequential Q and R bandings, clear C bands could still be achieved. Employing the prese
A 6-year-old girl of small stature and with some features of Turner's syndrome was found to have a karyotype with two-thirds of the cells possessing one, and one-third with two dicentric iso-long arm Y chromosomes. In metaphases with 46 chromosomes the majority of the abnormal Ys exhibited two prima
