title: [Gytogenetics of Chironomus riparius L. from the fishpond in Borok village (Diptera, Chironomidae)].
abstract: We have found three inherited inversions in Chironomus riparius populations from the Borok fishpond, namely: (A3d-B1a) in the arm A (C5a-C6a) in the arm D and (B3b-4d/e) in the arm F. Increase of heterochromatin in some bands of chromosome F (B3h, B3h + B3c--C1a) and puffs appearance in the arms C, D and E have been observed. We saw also changes in functional activity of nucleolar organizer (N) and Balbiani rings (BRe/BRb). It has been found that some of inversion breakpoints coincide with the Alu and Hinf satellite DNA localization sites.
