Abstract

The data on karyopool analysis of Chironomus plumosus from Novozybkov raion of Bryansk oblast, radioactively contaminated as a result of the Chernobyl accident, are presented. In the karyopool of this population, four types of heterozygous inversions (A1.2, B1.2, C1.2, D1.2) and a structurally small rearrangement in arm D, which is thought to be also associated with inversion, were identified. For inversions A1.2, C1.2, and structurally small rearrangement in arm D the cases of somatic mosaicism were described. The mean number of inversions per individual constituted 0.78. The number of genotypic combinations was 13. In 5% of the individuals chromosome B was identified, while 15.6% were polyploid (3n). In 1.8% of triploids somatic mosaicism for the level of polytene chromosomes was observed. Most of the larvae were characterized by partial asynapsis of the homologs in different regions of chromosome III. Specific features of the Chironomus plumosus karyopool from Novozybkov are thought to be associated with the habitation of a number of generations of this population on radioactively polluted territory.
