T. Mutafova et al., A COMPARATIVE CYTOGENETICAL ANALYSIS OF 2 NOTOCOTYLUS-EPHEMERA POPULATIONS (DIGENEA, NOTOCOTYLIDAE), Helminthologia, 32(4), 1995, pp. 229-231
A cytological study was carried out on Bulgarian and Slovak stocks of
Notocotylus ephemera (Nitzsch, 1817). The diploid number of chromosome
s was 2n = 20. A comparative analysis on the empirical data proved tha
t the populations studied differed significantly in several chromosome
s, mainly in the location of centromeres. The data showed an interpopu
lation polymorphism.
