Ak. Grishanin, TO PROBLEM ON CYTOTAXONOMY OF THE SPECIES CYCLOPS STRENUUS AND CYCLOPS KOLENSIS (COPEPODA, CYCLOPIDAE), Zoologiceskij zurnal, 75(12), 1996, pp. 1887-1892
The diploid number of chromosomes in Cyclops kolensis Lill. has been d
etermined, its karyotype is described. Cytogenetic characteristics of
the Cyclops strenuus Fischer population which differ from the previous
ly known ones have been obtained: 2n = 24; chromatine diminution in pr
esomatic germ cells during the 5th and 6th cleavages; accumulation of
eliminating chromatine in the equatorial plate region.
