Cytogenetic comparison of chironomid midge Glyptotendipes glaucus (Meigen, 1818) (Diptera, Chironomidae) populations from Northwest Russia and Ukraine (Chernobyl zone)
Functional characters of polythene chromosomes and chromosomal rearrangements in salivary glands of 177 larvae of Glyptotendipes glaucus (Diptera, Chironomidae) from reservoirs of Russia and Ukraine (Chernobyl) have been analysed. Similarity of the populations studied based on a pool of chromosomal reorganizations has been established. The general types of inversions in chromosomal arms A, B, D and E have been detected. Influence of radioactive pollution (Chernobyl) on functional changes of a nucleus, Balbiani rings, puffs, morphology of disks and interdisks is revealed.
