Abstract

One hundred normal American Blacks were studied by Q-banding technique in order to estimate the type and frequency of heteromorphisms in the centromeric regions of chromosomes 3 and 4. Heteromorphisms were classified using the scale of five intensity levels namely, negative, pale, medium, intense and brilliant fluorescence. QFQ intensity heteromorphisms [Formula: see text] for chromosomes 3 and 4 were 54.5 and 7%, respectively. The distribution of different intensities was significantly different in American Blacks compared with Caucasians.
