Cytogenetic Structure of <i>Chironomus balatonicus</i> Devai et al. Population in the Vistula Lagoon of the Baltic Sea
The analysis of Ch. balatonicus population cytogenetic structure shows that all seven chromosomal arms are polymorphous, the most polymorhous one is arm D, which was presented by four chromosome band sequences. Standard sequences as well as their zygotic and genome combinations prevail in the population. The presence of balD5, balD7 sequences in the population karyofund earlier recorded only in eastern populations and three new inversion band sequences (balB8, balF8, bal(EF)X) characterizes the cytogenetic structure as partly unique, formed under specific conditions of brackish water reservoir.
