Summary
The size of C-positive qh regions of chromosomes 1, 9 and 16 was determined using a Nikon-Vickers M85 microdensitometer. Results (area) were expressed based on how different they were from an average of each 1qh, 9qh or 16qh region in terms of standard deviations (SD). It was proposed that a variant within ±1 SD of an average be assigned to the intermediate class (class 3) in the Paris Conference system (Suppl. 1975), one within ±2 SD to either small or large class (class 2 or 4) and all others to either very small or very large (class 1 or 5). The present system compares favorably with any other methods so far tested as to the detection of a qh variant.
