title: RHG-band polymorphism of the short arms of human acrocentric chromosomes and relationship of variants to satellite associations.
abstract: The extent of RHG-band variation of short arms of human acrocentric chromosomes was investigated in a group of 100 subjects by visually comparing the variants with the size of reference bands 7p22, 21q22 and 11q13. Marked differences were found among the chromosomes in the distribution of variants; the largest mean size of RHG-band was associated with chromosome 21, whereas the variants of chromosome 22 had the smallest band size. The study further showed that the involvement of acrocentric chromosomes in satellite association did not depend upon the size of RHG-band variants.
