Chironomus balatonicus Devai, Wülker & Scholl View in CoL

The species has 2n = 8. AB and CD chromosomes are metacentric, EF—submetacentric, G—telocentric. The centromere regions of all chromosomes are well identified ( Fig. 5 View FIGURE 5 ). The band sequences in arm A are in an inverted state (A2.2). The smallest chromosome, G has three BRs and one NOR, one of the BR is not always expressed. The NOR and two BRs are situated at both ends of the chromosome. The chromosome has partial incomplete conjugation of the homologues. A chromosome marker is the two dark bands of chromosome G with several light ones in between ( Fig. 5 View FIGURE 5 ). A high chromosomal polymorphism, appeared by homo- and heterozygous inversions, was found in the polytene chromosomes of the species from areas after Chernobyl nuclear power events, a highly radioactive area near Kyiv ( Petrova & Michailova 1996). An additional B chromosome is reported for the first time in a species from this region ( Michailova & Petrova, 1994). One hundred and forty-six individuals were studied.
