Representative karyotypes of Ae. umbellulata (accession S234), Ae. markgrafii (accession AE1418), Ae. triuncialis (accession S197) and Ae. cylindrica after FISH with different repetitive DNA probes. The yellow signals on Ae. triuncialis chromosomes represent 45S rDNA with the sizes relevant to the intensity of produced signals. The probe combination on each genome chromosomes is presented at the bottom of the figure with the related colour.
