The investigations focused on tapeworms obtained as a result of the administration to individual rats a dose of 6 cysticercoids coming from the 39th and 40th generation of one-specimen inbred Hymenolepis diminuta - WMS il1. In 7.5-month old tapeworms the position of genital pores (PGP) was exclusively right-hand side with the genital ducts typical of this feature. Type 0p3a proglottids were the most common deviation from the typical number and topography of testes - 1p2a (one testis between the ovary and the genital pore marking the poral side and two testes on the aporal side) - in such tapeworms. Their mean incidence amounted to 8.9%, exceeding by at least 2.9% the mean quantitative value of this feature in tapeworms proceeding from non-inbred H. diminuta „strains" which have been subjected to similar studies. 19.5-month old tapeworms, exactly a year older than the previous ones, all had variable PGP. The number of PGP changes was here correlated positively with the number of type 2p1a proglottids and negatively with the number of type 1p2a and 0p3a proglottids.
