Abstract:
Intraspecific HindIII restriction fragment length polymorphism (RFLP) for the structural organization of the ribosomal gene cluster was described in Blattella germanica. In this species, homologous chromosomes were shown to contain ribosomal DNA (rDNA) repeats that differ in structure. The pattern of inheritance was determined for various structural variants of rDNA.
