In this study we investigated effect of chromium (VI) under laboratory conditions on genetic changes of wild type of D.melanogaster. The second chromosome of wild type flies was isolated and transferred either in homozygous(+′/+ ′) and heterozygous (+′/+ ″) state using Cy/Pm line. Individuals of this line contain dominant mutations (Cy – curly wings and Pm – plum eyes) and long inversions, which prevent recombination with analysed chromosomes, with the end result of stable heredity in the descendants. The +/Cy flies were fed a 0.01 percent solution of chromium (VI). Chromium (VI) solution was applied in both homozygotes (+′/Cy x +′/Cy) and heterozygotes (+′Cy x +″/Cy). The results showed that chromium (VI) treatment caused cut wings (ct) phenotype in some individuals.
