Statistical approach to the problem of the taxonomic status and evolutionary potential of a non-biting midge Prodiamesa olivacea Meigen (1818) (Diptera, Chironomidae, Prodiamesinae) based on karyotype analysis
The frequency of contacts of centromere and telomere regions of polytene chromosomes in the karyotype of a midge Prodiamesa olivacea has been analyzed. The fact of non-random frequency of centromere regions contacts has been confirmed by statistical methods. These data are consistent with the diploid number of chromosomes equal to 10. The species has been announced as a “transitional form”, evolving towards reduction of the chromosome number.
