Abstract
By using an appropriate scheme, various combinations of losses and gains of chromosomes I and II arising in oocytes of D. melanogaster were obtained. The frequencies of these combinations can be arranged as special sequences or patterns called aneuploidy patterns. Aneuploidy patterns were established for spontaneous, colchicine-induced and X-ray-induced exceptions and were highly specific for the agent tested. Such patterns can be obtained very quickly, because only exceptional progeny survive. By establishing aneuploidy patterns for chemical agents one would get information on the aneuploidizing action of the compounds tested.
