Two different Q patterns were found in BUdR and BCdR treated chromosomes of human lymphocyte cultures: X-type pattern, in which Giemsa and quinacrine banding both are reversed; Y-type pattern, in which Q-banding remains conventional in spite of reverse G-banding. Possible mechanisms of these finding

β¦ Synopsis
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 present technique, Q, R, and C polymorphisms can be recorded on a single metaphase.

## Abstract Structural abnormalities involving heterochromatic regions of the human genome are difficult to characterize because these segments are Gβband negative by GTG technique, a routinely used procedure in clinical cytogenetic laboratories. Chromosome abnormalities of such cases have gone und
The large heterochromatic chromosome of Drosophila nasutoides reveals distinctive C- and Q-bands. The regions which are negative in C-banding appear positive in Q-banding. The isochromosomic nature of this chromosome and the locality of the satellite DNAs in this chromosome are discussed with respec
A new technique is described which produces spiralization of human metaphase chromosomes. The important feature is heat followed by trypsin treatment. By varying conditions, it is possible to produce bands, spirals and intermediate stages. This provides a new approach to the understanding of banding
