Proposal for a scoring of the quality of the banding of chromosomes.

We propose an objective scoring of the quality of the banding of mitoses based on the number of bands (B), the length (L), and the width (W) of chromosome 7 in metaphase as used in the formula [LnB square root L/W]2. When no figure shows the quality of mitoses from which a breakpoint is described, this scoring could give information about it. It could be applied in cytogenetic cancer studies as well as for preparations with high resolution banding.
