Abbreviations: Capital letters represent sets of haploid genomes: E, Cobitis elongatoides; T, C. taenia; N, C. tanaitica. Shortcuts in the column captions: AOC, age of clones; NOI, number of individuals; NOMKA, number of metaphases karyologically analysed; NOGE, number of GISH experiments; NOAGM, number of analysed GISH metaphases.
In order to prepare probes for GISH experiments only gDNA was used from individuals marked with *.
