Chironomus plumosus (Linnaeus) View in CoL

The chromosome set is 2n = 8. Two chromosomes AB and CD are metacentric, EF—submetacentric and G chromosome is telocentric. The centromere regions of all chromosomes are distinct ( Fig. 11 View FIGURE 11 ). The arm A is with inverted sequences (A2.2). The species has four BRs—three in chromosome G and one in chromosome arm B. The homologues of chromosome G are unpaired. The NOR of chromosome G is near to the centromere region. Between the BR, located near to the NOR and the other BR there is a narrowing of the chromosome and many dark and light bands ( Fig. 11 View FIGURE 11 )—markers of the species. The species is highly polymorphous, characterized by the presence of a polymorphous system of inversions which involved the transition of a standard homozygous type of the karyotype through heterozygotization into another homozygous type ( Michailova 2014). This author reported for an additional B chromosome in Bulgarian populations ( Fig. 11 View FIGURE 11 ). Four hundred and two individuals were studied.
