Dv. Mukha et al., Intraspecific polymorphism for the structural organization of the ribosomal gene cluster in Blattella germanica, RUSS J GEN, 36(1), 2000, pp. 11-15
Intraspecific HindIII restriction fragment length polymorphism (RFLP) for t
he structural organization of the ribosomal gene cluster was described in B
lattella germanica. In this species, homologous chromosomes were shown to c
ontain ribosomal DNA (rDNA) repeats that differ in structure. The pattern o
f inheritance was determined for various structural variants of rDNA.
