[Relationship of the pseudosatellites, morphological characteristics and the associative capacity of acrocentric human chromosomes].

A sequential G-, C- and AgAS-staining of human acrocentric chromosomes showed the presence of polymorphism for silver-stained structures (pseudosatellites). Manifestation of pseudosatellites is positively correlated with the length of the secondary strangulation, amount of constitutive heterochromatin and associative ability of human acrocentric chromosomes. Pseudosatellites are supposed to be the remains of mitotically resorbed nucleolus.
